Villa Mazzanti

Villa Mazzanti: where it is and what it really is

There are places in Rome that you visit and places in Rome that you cross. Villa Mazzanti belongs to a third category, rarer and more interesting: it's a place you discover. It's on Via Gomenizza, around number 81, in that strip of the city where the Della Vittoria neighborhood stops being flat and starts climbing the eastern flank of Monte Mario. Below are the Tiber and the gymnastic architecture of the Foro Italico. Above, the woods. In between, behind a gate that very many Romans have driven past a thousand times without noticing, is a casino nobile set in a park.

The first thing to know up here is to lower your monumental expectations and raise your environmental ones. Villa Mazzanti is not Villa Borghese, it's not Villa Doria Pamphilj, it's not even Villa Torlonia. It has no gallery of masterpieces, no famous nymphaeum, it doesn't appear in the guides you buy at the airport. Villa Mazzanti is something different and in some ways more useful: it's the entrance gate, administrative and symbolic, to the system of protected natural areas of the City of Rome. Here, in the casino nobile, is the seat of RomaNatura, the regional agency that manages the reserves, parks and natural monuments that surround and penetrate the city.

Put another way: if you have ever wondered who decides what happens to the Marcigliana Reserve, who puts up the signs along the paths of the Insugherata, who keeps count of the kestrel nests above Decima Malafede, the answer has an address, and that address is this one. I find there's something deeply Roman in the fact that the office that administers more than 15,000 hectares of protected nature sits inside a 19th-century villa on a hill, and not in a glass tower in the suburbs.

Villa Mazzanti in one sentence

If I had to sum up Villa Mazzanti in one line for a friend passing through, I'd say it like this: a suburban villa on the slopes of Monte Mario, with a casino nobile overlooking the city and a park of holm oaks, pines, laurels, oleanders, cypresses, palms, catalpas and agaves, today the seat of the agency that governs Rome's protected areas. Every word of that sentence is a door, and here we try to open them all.

Why it's worth talking about at length

Because Villa Mazzanti is the point from which you understand Monte Mario, and Monte Mario is the point from which you understand Rome. It's not a paradox, it's geography. From the top of this hill you see the city laid out from north to south as on a cartographer's table, and anyone who has ever tried to explain the shape of Rome to someone seeing it for the first time knows how much a high vantage point is worth. Medieval pilgrims knew it very well. Whoever arrived from the north along Via Francigena saw the dome (or, before the dome, the Constantinian basilica) from up here, and up here wept for joy. The popular name of the hill, Mons Gaudii, the mountain of joy, comes exactly from that moment.

Villa Mazzanti and the eastern flank of Monte Mario

Monte Mario is the highest elevation of Rome inside the urban perimeter: it comes close to 139 meters above sea level, which in a city that along the Lungotevere sits around 10 or 12 meters means an enormous perceived difference in height. It isn't a hill like the Palatine or the Aventine, which are modest reliefs sculpted by the city. It's a real ridge, several kilometers long, oriented roughly from northwest to southeast, that separates the Tiber valley from the inland countryside toward Via Trionfale and the Cassia.

Villa Mazzanti sits on the slope that looks at the river. This detail, apparently technical, explains everything about the villa: it explains why it was built there, it explains the view, it explains the vegetation, it even explains the microclimate. The eastern slope gets the morning sun and stays in shade on summer afternoons, which in a city where in August it nearly reaches 40 degrees is not a minor detail. It's the reason why, under the holm oaks of this park, you can breathe in August.

The hill that isn't a hill

One of the most stubborn misunderstandings I hear repeated is that Monte Mario is the eighth hill of Rome. It isn't, and not out of place-name pedantry. The seven canonical hills (Palatine, Aventine, Capitoline, Quirinal, Viminal, Esquiline, Caelian) all sit on the left bank of the Tiber and are, geologically, the remaining spurs of a single bank of tuff cut by watercourses. Monte Mario sits on the right bank, belongs to another geological story and another urban history. Together with the Janiculum and the Vatican it forms the hill system of the right bank, the one the ancient Romans considered outside the city in the full sense.

This estrangement protected Monte Mario for centuries. While the Rome of the popes thickened inside the bend of the Tiber, here there remained vineyards, vegetable gardens, farmhouses and convents. The city arrived only at the end of the 1800s and bit into the foot of the hill. The upper part resisted, and still resists, and that is why today we can talk about a nature reserve a stone's throw from Piazza del Popolo.

What you see from the park of Villa Mazzanti

From the open clearings of the park, and even better climbing toward the summit of the reserve, you see a slice of city worth the trip on its own. In the foreground the Tiber and the Foro Italico, with the Stadio Olimpico and the Ponte Duca d'Aosta. A little farther the Palazzo della Farnesina, the gigantic travertine parallelepiped that houses the Ministry of Foreign Affairs, begun in the 1930s as the Casa Littoria and completed after the war with another purpose and another name. In the background, the dome of St. Peter's, the Vittoriano, and on days with a north wind the chain of the Prenestini Mountains and the Castelli.

The best moment is the hour before sunset on a day with a north wind, usually between November and March. The raking light draws the reliefs, the air is clear, and the city below goes from gray to ocher to pink in about 40 minutes. Whoever photographs knows it. Whoever doesn't photograph discovers it.

The casino nobile of Villa Mazzanti

The built heart of the villa is the casino nobile, the main building that today houses the offices of RomaNatura. It's a construction of late 19th-century layout, of the kind that in Rome are called "villini" with a generous euphemism: two floors above ground plus a service level, compact plan, regular openings, the typical arrangement of the bourgeois country residences built in the season when the new capital of the Kingdom began to eat up the surrounding countryside.

It isn't a building that shouts. It's a building that stays in its place, with the sobriety of something designed to be lived in during the summer and to look at the landscape rather than to be looked at. The facade toward the valley is the important one, because it's the one that opens onto the panorama. The rest follows.

The casino nobile type: a useful aside

It's worth spending a couple of words on what "casino nobile" means, because it's a term that recurs everywhere in guides and that almost nobody explains. In the organization of the Roman suburban villa, from the 1500s on, the complex is articulated into parts with different functions. The casino nobile is the owner's residence, the building for show, the one with the good rooms and the loggia. Around it gravitate the casale or farmhouse, where those who work the land live, the stables, the barns, the cellar, the lemon house, sometimes a chapel. The park in turn divides into a formal garden near the house, a grove or barco farther away, and productive land (vineyard, olive grove, vegetable garden) that pays the expenses.

This three-part structure, manor house plus farm plus garden, is the most lasting invention of Italian villa civilization, and you find it identical from Hadrian's Villa at Tivoli to the bourgeois properties of 19th-century Rome, with 700 years of variations on the theme. Villa Mazzanti sits in the last season of that story: the season in which the owners are no longer cardinals and princes but professionals, merchants, officials of the new unified administration.

The interior and its use

Today the building is a public office in every respect, with what follows: desks, binders, cartography hung on the walls, meeting rooms carved out of spaces born for something else. It isn't a house museum and doesn't claim to be. Whoever goes in goes in for paperwork, for a meeting, for one of the environmental education initiatives the agency organizes. Don't expect historic furnishings or visitor routes: expect a historic building that keeps working, which is, after all, the best fate that can befall a building.

The park of Villa Mazzanti and its species

The description circulating of the park of Villa Mazzanti lists holm oaks, pines, laurels, oleanders, cypresses, varieties of palms, catalpas and agaves. It's a list that deserves to be read slowly, because it tells two overlapping stories: that of spontaneous Mediterranean vegetation and that of 19th-century ornamental taste.

The holm oak: the founding tree

The holm oak, Quercus ilex, is the evergreen oak of the Mediterranean, and it's the tree that defines Monte Mario. It has leathery leaves, dark green above and whitish below, able to reduce transpiration during the summer drought. It has a dense crown that produces deep shade and an understory poor in grasses but rich in leaf litter. An adult holm oak can exceed 20 meters and live for centuries. The holm oak wood is the potential vegetation of a large part of the Italian Tyrrhenian slope, and in Rome precious patches of it remain: Monte Mario itself, the Insugherata, the Tenuta dei Massimi.

Walking in a holm oak grove in August is a physical experience before an aesthetic one. The temperature drops by quite a few degrees compared to the asphalt, the noise is muffled, the light becomes green and grainy. It's the reason why Romans have built villas on these slopes for 2,000 years.

The stone pine and the silhouette of Rome

The stone pine, Pinus pinea, is the tree that in the collective imagination means Rome, and it must be said with some honesty that it is largely a modern invention. The umbrella pines we see along the consular roads and in the villas are to a very large extent the result of 19th- and 20th-century plantings, often with scenic intentions: the stone pine grows fast, makes an unmistakable profile and produces pine nuts. Ottorino Respighi would not have written The Pines of Rome in 1924 if those pines had not been, back then, a relatively recent and much admired visual novelty.

Today Roman pines have a serious problem, and whoever frequents the parks has noticed it: Toumeyella parvicornis, the pine tortoise scale, an insect native to North America that arrived in Italy in recent years, which produces honeydew, promotes sooty mold and weakens the trees until it kills them. The yellowed crowns and the sticky dripping under the pines of half the city come from there. It's one of the plant health emergencies that the managing bodies of Roman parks, RomaNatura included, deal with daily.

Laurel, oleander, cypress: the Mediterranean garden

The laurel, Laurus nobilis, is the plant most loaded with meaning in the classical repertoire: its leaves were woven into the crowns of triumphators and poets, and its presence in a Roman garden is never entirely accidental. It's also, prosaically, an excellent hedge shrub: it tolerates pruning, grows in shade, smells good when you brush it.

The oleander, Nerium oleander, is the flower of the Roman summer: pink, white, deep red, it withstands drought, dust and smog, which is why it's found on the traffic islands of half the city. It's also poisonous in every part, leaves, flowers and wood, and it's worth remembering for those walking with children or dogs.

The cypress, Cupressus sempervirens, is the vertical tree par excellence, the one that in gardens serves to mark axes, avenues and boundaries. In the Mediterranean tradition it is associated with places of burial and meditation, but in the Italian villa it mainly has a compositional function: it gives rhythm, like a column in a portico.

Palms, catalpas and agaves: 19th-century exoticism

Here we enter the most revealing chapter. Palms, catalpas and agaves do not belong to the spontaneous flora of Lazio. They are ornamental introductions, and their presence dates the garden with the precision of a postmark.

Palms, in particular Phoenix canariensis and Washingtonia, explode in European gardens between the mid 1800s and the early 1900s, in the season of orientalism, world's fairs and commercial nurseries that suddenly make accessible species that were previously greenhouse-only. A palm in front of a villino meant modernity, travel, the world. Palms too, today, have their enemy: the red palm weevil, Rhynchophorus ferrugineus, which since the 2000s has decimated the date palms of the whole Mediterranean.

The catalpa, Catalpa bignonioides, comes from the southeastern United States. It has enormous heart-shaped leaves, white flowers spotted with yellow and purple in June, and very long hanging pods that make it unmistakable in winter. It's the shade tree of 19th-century avenues par excellence: it grows fast, takes pruning well, makes a vast canopy.

The agave, Agave americana, comes from Mexico and arrived in Europe in the 1500s with the first cargoes from the New World. Its rosette of fleshy thorny leaves and its colossal flower stalk (which can exceed eight meters and which the plant produces only once, before dying) made it a fetish of romantic gardens. Finding it in a Roman park means that someone, a century and a half ago, wanted a piece of American desert under Monte Mario.

Villa Mazzanti as the seat of RomaNatura: what it means

RomaNatura is the regional agency for the management of the system of protected natural areas in the City of Rome. It was born at the end of the 1990s, within the framework of Lazio's regional legislation on protected areas, with a mandate as simple to state as it is complicated to carry out: to hold together, administer and keep alive the portions of nature that survived inside and around the most extensive municipality in Europe.

Because it's a fact that always surprises whoever hears it for the first time: the territory of the City of Rome is enormous, over 1,200 square kilometers, and a very significant share of that territory is not built city but countryside, woods, pasture, river, marsh. RomaNatura administers about 15,000 hectares of this heritage. 15,000 hectares is 150 square kilometers: more than the urbanized surface of many European capitals.

An agency inside a villa

That the seat is at Villa Mazzanti isn't a colorful detail. It's coherent. An agency that deals with urban nature reserves works inside an urban nature reserve, on the ridge that is both the most visible and the most fragile case of its mandate. Whoever works in those offices, when they look up from the monitor, sees exactly the problem they're managing: the woods on one side, the city pressing on the other.

What it concretely does

The functions of a park agency are less romantic than you'd imagine and more decisive. Surveillance and policing. Planning, meaning the drafting of the management plans that establish what can be done in each zone. Issuing opinions and clearances on building, agricultural and infrastructure works that fall within the protected perimeter. Maintenance of trails and signage. Monitoring of flora and fauna. Emergency management, from summer fires to the felling of dangerous trees. And a vast environmental education effort aimed at schools.

This last point deserves attention. The Roman classes that go up to spend a day in the woods, that learn to tell an oak from a holm oak or to distinguish the call of a great tit, pass through the system that has its center here. It's invisible and cumulative work, the kind measured in decades.

The system of protected areas managed by RomaNatura

To truly understand Villa Mazzanti you have to understand what is administered from here. The system includes nature reserves, urban parks and natural monuments spread over every quadrant of the city. I describe the main ones, because each is a possible discovery for someone who has already seen the Colosseum.

The Monte Mario Nature Reserve

It's the one on which Villa Mazzanti stands: a few hundred hectares along the ridge, with holm oak grove, Mediterranean scrub, clearings and the remains of old noble estates. It's the most urban of the reserves, the one where the border between woods and buildings is sharpest and most permeable.

The Insugherata Nature Reserve

It lies immediately to the north, between Via Trionfale and the Cassia, and takes its name from the cork oaks that grow there. It's a long narrow valley, with ditches, wet meadows and woods of downy oak and Turkey oak. Scenically it's one of the biggest surprises of the northern quadrant, because in a few minutes' walk you lose sight of the city completely.

The Marcigliana Nature Reserve

In the far northeast, toward the Salaria and the Nomentana, it's the great agrarian landscape of the Agro Romano: gentle hills cultivated with wheat, rows of vines, isolated farmhouses, tree-lined ditches. Whoever has in mind the 18th-century views of the Roman countryside finds them here, almost intact.

The Decima Malafede Nature Reserve

It's the largest of the system, in the south toward Pomezia and Via Pontina: thousands of hectares of woods, arable land and scrub, with important wildlife and widespread archaeological traces. It's so big that you can walk half a day in it without meeting anyone.

The Valle dell'Aniene Nature Reserve

It follows the course of Rome's second river in the eastern urban stretch, between Ponte Mammolo and the confluence with the Tiber. It's the most heavily used reserve, because it crosses populous neighborhoods and works as a lung and an ecological corridor at once.

The other reserves and the natural monuments

The system also includes the Valle dei Casali Reserve, on the Portuense, with its farmhouses and olive groves, the adjacent Tenuta dei Massimi, with woods and gorges, the Tenuta di Acquafredda, on the Aurelia, the Laurentino Acqua Acetosa, to the south, the Parco Urbano del Pineto, which I'll cover separately because it ideally borders Monte Mario, and natural monuments such as the Palude di Torre Flavia, on the coast north of Ladispoli, and Galeria Antica, with its abandoned medieval village on a spur of tuff.

Put in a row, these places draw a green crown around the city that very few capitals possess and that almost no Roman knows in full. Villa Mazzanti is the center of that crown.

The Monte Mario Nature Reserve: the woods of Villa Mazzanti

The reserve that surrounds Villa Mazzanti is a textbook case of urban nature. It extends along the ridge for a few kilometers, including areas of public and private ownership, historic villas, remaining farmland, and of course the woods.

What grows there

The dominant formation is the holm oak grove, with specimens of notable size in the less disturbed areas. Beside it are the downy oak, Quercus pubescens, which is the deciduous oak of warm exposures, the hop hornbeam, the manna ash, the strawberry tree, the mastic, the mock privet, the Mediterranean buckthorn, the butcher's broom. On the edges and in the clearings the scrub opens into meadows that in May explode with wild orchids, and yes, in Italy wild orchids exist and they are dozens of species, small and extraordinary.

Then there are the adventive and weedy presences that accompany every urban wood: the ailanthus, Ailanthus altissima, the tree of heaven, which arrived from China in the 1700s as an ornamental plant and became one of the most aggressive invaders in Europe. The black locust. The Hottentot fig on exposed embankments. The fight against the ailanthus is one of the least rewarding and most necessary activities a park agency carries out.

Who lives there

The fauna of Monte Mario is the kind typical of Mediterranean peri-urban woods, with a few surprises. Among the birds: the great spotted woodpecker, the green woodpecker, the jay, the wood pigeon, the hoopoe in the clearings, the little owl and the tawny owl at night, and above the clearings the kestrel hunting with its motionless hover, the "spirito santo" as the hunters call it. In the migration months the ridge works as a route, and whoever knows how to look sees raptors passing through.

Among the mammals, the fox is by now a stable and unselfconscious presence across the whole Roman periphery. There are the porcupine, which leaves its quills on the paths and digs conspicuous burrows, the badger, the weasel, the hedgehog, several bats. And there's the wild boar, which in the last decade has become the great protagonist of the Roman urban edges: a story that joins ecology, waste management and political controversy, and one we'll come back to.

The value of a corridor

An isolated urban wood is an island, and biological islands lose species over time. The real value of Monte Mario lies in the fact that the ridge connects, even if with bottlenecks, the Insugherata Reserve to the north and the Parco del Pineto to the south, and from there the system opens toward the countryside. Preserving the continuity of these corridors is perhaps the hardest and least visible task of urban environmental planning: a road, a construction site, a fence in the wrong spot is enough to cut a flow that took centuries to form.

The geology of Monte Mario and the fossils under Villa Mazzanti

Here comes the part that surprises almost everyone. Monte Mario is not just any hill. It's a reference locality of Italian geology, and its name has entered the international scientific lexicon.

The sea that was here

The clays and sands that form the core of the hill were deposited on the floor of a sea, in the Pliocene and the Lower Pleistocene, between about 3 million and a million and a half years ago. That sea covered the area of present-day Rome. The hills of the right bank are, originally, marine sediments that were uplifted and then cut by rivers. The tuff that characterizes the hills of the left bank comes later, from the great volcanic complexes of the Alban Hills and the Sabatini, between 800,000 and 300,000 years ago.

In the clays of Monte Mario marine fossils are preserved in extraordinary quantity: mollusks, brachiopods, corals, foraminifera. The 19th-century collections made on this hill ended up in the great Italian paleontological collections, and generations of natural science students at the University of Rome learned stratigraphy walking up here with a hammer in hand.

The "Monte Mariano" geological stage

The Monte Mario sequence gave its name, in the historical geological literature, to a stratigraphic interval of the Pleistocene. The nomenclatures have changed over time and the matter is technical, but the point remains: this hill is a type section, a place that geologists from half the world have cited in their work. Walking in the park of Villa Mazzanti knowing that underfoot is a seafloor from 3 million years ago changes the experience of the walk a little.

Why the hill slides

The geological makeup also explains a practical problem that has afflicted Monte Mario forever: the stability of the slopes. The Pliocene clays, when they soak up water, slip. Roman chronicles are full of landslides, collapsed retaining walls, roads closed on the slope that descends toward the Tiber. It's one of the reasons why the upper part of the hill was not built up like the rest of the city, and why the vegetation has a functional role and not just an aesthetic one: the roots hold the slopes.

The name of Monte Mario and its metamorphoses

Few Roman place names have changed skin as much as this one, and reconstructing the sequence is a small exercise in linguistic archaeology that I recommend to anyone who climbs to Villa Mazzanti.

From the Clivus Cinnae to the Mons Malus

In Roman times the area fell within the broad district that the sources call generically Vaticanus, a term that indicated the whole sector of the right bank north of the Janiculum, and that has an Etruscan or in any case pre-Latin root of disputed meaning. The slope was crossed by a road known as Clivus Cinnae, the slope of Cinna, from the name of an owner or of a figure of the gens Cornelia. In the medieval period the hill appears as Mons Malus, the bad or ill-famed mountain, perhaps for the insecurity of the roads outside the gate, perhaps for the sterility of the clay soils.

Mons Gaudii: the mountain of joy

Then come the pilgrims. Whoever came down from the north along the Francigena, after weeks of walking from Canterbury or from Aachen, crossed this ridge and for the first time saw Rome. The reaction is documented by centuries of travel diaries: people wept, knelt, raised a cross. Hence the name Mons Gaudii, the mountain of joy, which in Old French becomes Montjoie and which has left place-name traces in half of Europe along all the great pilgrimage routes.

I find it one of the most beautiful ideas you can bring to Villa Mazzanti: that this ridge was, for almost a thousand years, the place where a journey ended. Not the arrival, but the moment immediately before the arrival, the one in which the destination becomes visible and the effort takes on meaning.

From Mario to Monte Mario

The current name consolidates in the 1400s and derives, according to the most accredited tradition, from Mario Mellini, a member of a Roman family that owned vast properties here and that built the villa later famous as Villa Mellini. It has nothing to do, then, with Gaius Marius, the consul and reformer of the republican army, although the misunderstanding is inevitable and recurring. It's the typical case in which a family place name is backdated by the collective imagination to a more illustrious figure.

The Astronomical Observatory and the Astronomical Museum above Villa Mazzanti

Climbing from the park of Villa Mazzanti toward the top of the ridge you meet one of the oldest and least visited scientific institutions of the city: the astronomical observatory of Monte Mario, set inside and around Villa Mellini.

Why an observatory here

The reason is the same as for a villa: height and air. In the first half of the 1900s the observatory of the Collegio Romano, right in the center, was by then smothered by the lights and vibrations of the city. The move to Monte Mario, decided in the 1930s, answered a precise technical need: to get away from light pollution and gain altitude. With the irony that history reserves for these things, today Rome's light pollution has amply reached Monte Mario too, and real scientific observation is done elsewhere, in the mountains or in the southern hemisphere.

The Astronomical Museum and the Solar Tower

What remains, and what is worth the climb, is a museum. The astronomical and Copernican collections preserve instruments, telescopes, celestial globes, sundials, armillary spheres and a library holding of enormous value, with early editions of the works of Copernicus, Galileo, Kepler. Then there's the solar tower, built for the study of the Sun, with its vertical structure and the play of mirrors that carries the solar image to a laboratory below.

Visits take place on the initiative of the national institute of astrophysics, generally on scheduled openings and observation evenings. Whoever organizes an afternoon at Villa Mazzanti would do well to check in advance if there are openings on the calendar: the combination of woods plus astronomical museum plus sunset over the city is, without exaggeration, one of the best-spent Roman days.

Villa Mellini

The villa that houses the observatory has a 15th-century layout, reworked several times over the centuries. It belonged, as mentioned, to the Mellini, who gave their name to the hill. It then passed to other owners and finally to the State. It's the most important historic building of the ridge, and its terrace offers the panorama that made Monte Mario famous in early modern views.

Villa Madama: the masterpiece seen from the slope of Villa Mazzanti

On the same slope, a little farther south, stands what is probably the most important villa of the Roman Renaissance after the Farnesina: Villa Madama. It cannot be freely visited (it belongs to the Italian State and is used by the Ministry of Foreign Affairs for institutional representation), but its profile can be read from the slope, and its story has to be told because it explains what it meant to build on these hillsides.

Raphael's design

The villa was commissioned around 1518 by Cardinal Giulio de' Medici, cousin of Pope Leo X and future Pope Clement VII. The design is by Raphael, and it is the Renaissance's most ambitious attempt to reconstruct, on a philological basis, the ancient Roman villa described by Pliny the Younger in his letters: a complex articulated in circular courtyards, loggias, a theater, terraced gardens, nymphaea, a hippodrome, with a hierarchy of spaces that descended from the mountain to the river.

Raphael died in 1520 and the work site passed to Antonio da Sangallo the Younger and to Giulio Romano. The stucco and grotesque decorations of the great loggia are the work of Giulio Romano and Giovanni da Udine, and it is perhaps the most refined cycle of grotesques of the Roman 1500s: a repertoire of monsters, festoons, animals and fantastic architecture derived from direct study of the vaults of the Domus Aurea, rediscovered a few decades earlier.

The Sack of Rome and the unfinished work

Villa Madama was never finished. In 1527 the landsknechts of Charles V, during the Sack of Rome, set it on fire, and the work site never resumed according to the original design. What we see today is about a third of what Raphael had drawn: the loggia, the half circular courtyard, the hanging garden, the nymphaeum with Giovanni da Udine's elephants. The rest stayed on paper.

The name comes from Margaret of Austria, natural daughter of Charles V and wife first of Alessandro de' Medici and then of Ottavio Farnese, who owned it in the 1500s: "Madama" was the title by which the Romans designated her, and from her also take their name Palazzo Madama, today the seat of the Senate.

What you see of it

From the slope of Monte Mario, and at certain points from the paths of the reserve, you glimpse the complex set in greenery above the Foro Italico. It's a view from afar, but enough to understand the layout: the villa sits halfway up the slope, oriented toward the Tiber, with the terraced garden that exploits the difference in height. Exactly the same settlement logic as Villa Mazzanti, three and a half centuries later and with an incomparably more powerful patron.

Forte Braschi and the entrenched camp of Rome

Not far from Villa Mazzanti, on the ridge, there is a presence that throws off whoever arrives thinking only of the woods: a 19th-century military fort, still used by the Armed Forces.

Why Rome has 15 forts

After 1870, when Rome becomes the capital of the Kingdom of Italy, the new State faces a strategic problem: the city is indefensible. The Aurelian Walls, however imposing, offer no resistance to modern artillery. Between 1877 and the early 1890s the so-called entrenched camp of Rome was therefore built: a belt of 15 forts and four batteries, arranged radially a few kilometers from the center, designed for crossfire and for controlling the access roads.

The names are those of the localities or gates they guarded: Forte Aurelia, Forte Boccea, Forte Braschi, Forte Trionfale, Forte Monte Antenne, Forte Pietralata, Forte Portuense, Forte Ostiense, Forte Ardeatino, Forte Prenestino, Forte Casilino, Forte Tiburtino, and others. They never fired a shot in war: the evolution of artillery made them obsolete before they were even completed. It is perhaps the biggest useless military investment in the history of unified Italy, and for exactly this reason almost all of them have been preserved.

Forte Braschi today

Forte Braschi guards the Monte Mario sector. The structure is the typical one: moat, embankment, casemates, powder magazines, a polygonal plan designed to be invisible from outside. Today it hosts military installations and is not open to the public. Its perimeter, however, has had an interesting side effect: by withdrawing dozens of hectares from construction for a century and a half, the forts functioned as unwitting nature reserves. Several of them are today public parks or green areas, and their belt surprisingly coincides with that of the protected areas.

The fate of the Roman forts

Some forts have had remarkable second lives. Forte Prenestino has been since the 1980s one of the historic social centers of Italy. Forte Portuense and Forte Antenne are green areas. Forte Ardeatino and Forte Boccea still host military functions, the latter with the military prison. Telling the story of the belt of forts means telling a century and a half of Italian history in negative, through what was built for a war that never came.

The Parco Urbano del Pineto: the neighbor of Villa Mazzanti

On the other slope, the one that descends toward the Aurelia valley, opens one of the most beautiful and least known parks of Rome: the Parco Urbano del Pineto, also managed by RomaNatura, and therefore also administered from Villa Mazzanti.

A canyon inside the city

The Pineto occupies a broad valley between Monte Mario, the Pineta Sacchetti and the Balduina and Torrevecchia area. Whoever enters for the first time has a constant reaction: surprise. The valley is deep, the slopes are steep, the vegetation is thick, and from the bottom the city disappears completely. There are open meadows, pine groves, ditches, and a geography that seems rural even though the buildings overlook it from 200 meters away.

The Valle dell'Inferno and the kilns

The part of the district that descends toward the Vatican bore a memorable name: Valle dell'Inferno. The name doesn't derive from diabolical legends but from an industrial fact: here, from the 1500s to the 1800s, clay was extracted and the bricks that built St. Peter's and half of modern Rome were fired. The kilns worked day and night, the smoke covered the valley, the glow of the furnaces could be seen from above. A hell, literally.

The community of kiln workers was for centuries one of the most characteristic and poorest social groups of the city: brutally hard work, precarious housing, endemic malaria. Pier Paolo Pasolini set in this area some pages and some shots of his Roman works, and the neighborhood that grew from it, Valle Aurelia, still carries in its place names the memory of the kilns.

The casale and the paths

Inside the park a historic casale is preserved, with the typical look of the rural buildings of the Agro: compact body, dovecote tower, courtyard, farm outbuildings. It's the kind of building that dotted the whole Roman countryside and of which a few hundred examples remain today, often in a precarious state. The Pineto paths can be walked and in part cycled, and let you cross the valley from one side to the other in a good hour of walking.

The villas and casali of the Agro Romano: the family Villa Mazzanti belongs to

Villa Mazzanti can't be understood in isolation. It belongs to a vast and largely forgotten category: the suburban properties of the Agro Romano. It's worth reconstructing their history, because it is the history of the landscape we live in.

From the ancient villa to the papal vineyard

In Roman times the countryside around the city was dotted with rustic villas and villas of otium: farms with a residential part, some modest, others sumptuous. The late antique and early medieval demographic collapse emptied the territory. The countryside depopulated, the land went back to pasture and woods, and property concentrated in the hands of the Church and the great monasteries.

From the 1400s, with the stable return of the popes to Rome and the economic recovery, the season of the vigne begins: fenced plots, cultivated with vines and vegetables, with a small casino for the owner and a house for the vine keeper. The vigne surrounded the city in a continuous band just outside the walls, and were owned by cardinals, prelates, merchants, confraternities. From this modest type, through successive growth, many of the Roman villas were born.

The 1500s and 1600s: the grand villa

The golden century of the Roman villa is the one that runs from Villa Madama to Villa Doria Pamphilj: 150 years in which the papal families build enormous complexes with a casino for show, formal gardens, hunting woods, water theaters, collections of antiquities. Villa Giulia, Villa Medici, Villa Borghese, Villa Ludovisi, Villa Montalto, Villa Albani, Villa Doria Pamphilj: the crown of green that surrounded Rome in the 1700s has no equal in Europe, and Grand Tour travelers describe it with amazement.

The 1800s: the bourgeois villa, with a lowercase v

After Unification everything changes. The great families go into debt, many villas are subdivided into lots (Villa Ludovisi becomes the neighborhood of the same name, Villa Massimo and Villa Patrizi are largely erased), and at the same time a new demand is born: that of the professional and commercial bourgeoisie of the capital, who want their country house half an hour by carriage from the center.

It is in this market that dozens of suburban villini are born on the hills around Rome, Monte Mario included. They are properties of medium scale, with a sober casino nobile, a park designed according to the English landscape taste or a reduced Italian one, and a part still productive. Villa Mazzanti belongs to this family, and its name (a family surname, not a noble title) confirms it.

The 1900s: disappear or survive

The fate of these properties in the 1900s has almost always been one of two: subdivision into lots or public acquisition. The city grew at an impressive speed (Rome goes from about half a million inhabitants in 1900 to over 2.5 million in the 1960s) and devoured the ring of villini. Those that were saved almost always owe it to a restriction, an expropriation or a donation. Villa Mazzanti is among the survivors, and its present use as the seat of the park agency is, if you think about it, the most coherent form of survival possible.

The neighborhood around Villa Mazzanti: Della Vittoria and Trionfale

Via Gomenizza sits in a precise urban fabric, and reading it helps you understand where you are.

The street names tell a war

The Della Vittoria neighborhood is born in the 1920s and 1930s, and its place names are an open-air political monument: the streets bear names of localities of the Great War and the eastern Adriatic. Gomenizza is the Italian form of Igoumenitsa, a city of Greek Epirus. And around it are streets dedicated to Sabotino, Podgora, Oslavia, Monte Zebio, Vodice, Zara, Sebenico, Pola, Fiume, Trieste, Trento. It's an atlas of borders, many of which no longer exist in that form today.

Walking in this neighborhood reading the street signs is an exercise in contemporary history. Every name is a battle, a contested city, a piece of that eastern border that crossed the Italian 1900s with dramatic outcomes. You don't need to take a position to recognize that the neighborhood is a document.

The Foro Italico below the hill

At the foot of the slope is the Foro Italico sports complex, built starting in the early 1930s as the Foro Mussolini to a design by Enrico Del Debbio and then Luigi Moretti. It includes the Stadio dei Marmi, with its 60 statues of athletes in Carrara marble donated by the Italian provinces, the Stadio Olimpico, rebuilt several times and today home to Roma and Lazio, the monolithic Carrara marble obelisk over 17 meters high, the plaza with the black and white mosaics, the Academy of Physical Education, and the covered pool with its mosaics.

It is the most coherent and best preserved complex of rationalist and monumental architecture from the 20 years of fascism in Italy, and the fact that it is still fully in use (Serie A is played there, the Internazionali tennis tournament is run there a stone's throw away) makes it a case study in living with the architectural legacy of fascism. From Villa Mazzanti you look at it from above, and it's the best perspective for grasping its overall layout.

The Farnesina and the bridge

Next to it, the Palazzo della Farnesina: begun in 1937 as the seat of the National Fascist Party, interrupted by the war, completed in the 1950s and assigned to the Ministry of Foreign Affairs, where it still is. It is one of the largest buildings in Italy, with a volume of hundreds of thousands of cubic meters, and it holds a notable collection of contemporary art.

The Ponte Duca d'Aosta, which connects the Foro Italico to the left bank, dates from 1939 and has four large reliefs celebrating the Third Army in World War I. Together, bridge, obelisk, stadium and ministry make up the only completed 20th-century monumental axis of Rome, and Monte Mario is its natural backdrop.

How to get to Villa Mazzanti

Access is from Via Gomenizza, in the stretch that climbs toward the ridge starting from the area above the Foro Italico. It's an address that not all taxi drivers recognize at first try, so it's best to go knowing what you're looking for.

On foot, which is the right way

The advice, for those with legs and half an hour of time, is to climb on foot starting from the Lungotevere. You cross the Ponte Duca d'Aosta, skirt the Foro Italico and start climbing. The difference in height is real, about 100 meters, but the climb is gradual and gives a succession of glimpses of the city that no public transit can offer. It's also the way this hill has been walked for centuries: whoever arrived in Rome from the Francigena climbed it on foot or by mule.

By public transit

The quadrant is served by the surface lines that climb from the Mazzini area and from Piazzale Clodio toward Monte Mario and the Balduina. The reference railway station for the upper part of the hill is Monte Mario, on the urban line that connects the northwest quadrant. The nearest subway is line A at the Ottaviano stop, from which, however, you need a transfer. Runs and routes change over time, so it's best to check updated itineraries the same day.

By car and by bicycle

By car the climb is easy but parking in the upper part is what it is: narrow streets, residents, and a stretch of Via Gomenizza that doesn't forgive reckless maneuvers. By bicycle the climb is demanding but not prohibitive. With an electric-assist pedal it becomes a stroll, and the descent toward the Tiber is one of the few stretches of Rome where you can truly enjoy a drop in elevation.

The useful number

The phone reference associated with the seat is that of the agency that manages the reserves, RomaNatura: the updated numbers are on the contacts page of the official site. It's good for general information on the reserves and the initiatives. For a specific visit to the park it's always best to ask first, because part of the area belongs to public offices and is not a freely accessible garden like Villa Borghese.

The seasons at Villa Mazzanti

An urban wood is never the same place twice, and Villa Mazzanti changes character four times a year sharply enough to justify four visits.

Spring

Between March and May the understory lights up. Spring cyclamen, squill and wood anemone bloom in the cooler zones. In the open clearings the wild orchids appear, which in Rome are more plentiful than people imagine: Ophrys with their flowers that imitate pollinating insects, Orchis, Serapias. The birds sing from dawn, the migrants return, and the air has a clarity that will not come back in summer.

It's also the period when the woods are most fragile: nesting is under way, and leaving the paths means disturbing broods that are on the ground or in low bushes. This is the moment when the rules of a protected area stop being bureaucracy and become common sense.

Summer

From June to September the value of Villa Mazzanti is thermal even before it is scenic. Under the holm oak grove it's even eight or 10 degrees cooler than on the asphalt of Viale Angelico, and whoever has tried a Roman July afternoon knows what that means. The woods are silent, the cicadas cover everything, the panorama is lost in the haze. It's the worst season for photographing the city and the best for being inside it.

It's also the fire-risk season, which on a dry and windy ridge is a very serious and recurring danger. Roman news records every summer fires on the slopes of Monte Mario, often of arson or negligent origin. There's no need to say that lighting anything up here is banned and senseless.

Autumn

October and November are the best moment of all. The first storms clean the air, the temperature is perfect for walking, the mixed wood takes on color because beside the evergreens there are downy oaks and manna ashes that turn yellow. It's the season of mushrooms and acorns, and therefore of wild boar, porcupines and jays that bury them everywhere, contributing, without knowing it, to planting tomorrow's wood.

Winter

With the north wind the air becomes glass. These are the days when from Monte Mario you can see the snowy Simbruini, the profile of Mount Soratte to the north, the Castelli to the southeast, and the city in a detail that doesn't exist in summer. It's cold and windy, but for anyone seeking the view there's no comparison. The holm oak wood, being evergreen, stays full even in January: it's one of the few Roman walks that in winter doesn't give the impression of crossing a skeleton.

Environmental education: what is done at Villa Mazzanti

A substantial part of the activity that starts from this seat concerns schools. It's the least visible and most important chapter of the whole story.

Classes in the woods

The reserves of the system host thousands of students every year in guided programs: recognition of tree species, observation of fauna, reading of the agrarian landscape, workshops on soil and water. Whoever has accompanied a third-grade class into a holm oak grove knows that the effect is not didactic but anthropological: many of those children have never walked in a wood, and the first reaction is almost always silence.

Environmental citizenship

Besides the schools there are initiatives aimed at citizens: guided walks, volunteer cleanup days, participatory wildlife censuses, informational meetings. Rome has a strong environmental association tradition, made of neighborhood committees, hiking groups, national naturalist associations with local chapters. Much of the ordinary maintenance and informal oversight of Rome's urban parks, it must be said frankly, is the work of volunteers.

The problem of numbers

It's worth being honest: managing 15,000 hectares with the resources of an Italian public agency is an exercise in difficult arithmetic. The ratio between available staff and the surface to be guarded is such that capillary surveillance is materially impossible. Whoever frequents the Roman reserves knows the symptoms: illegal dumps in the ditches, motocross off the trails, loose dogs in nesting areas, unauthorized fences. It's not ill will. It's a structural disproportion, and knowing this helps you behave better when you are inside.

The trails of the Monte Mario Reserve around Villa Mazzanti

The reserve can be walked, with some caution and some attention to the signage, along a network of paths that connect the urban entrances to the ridge.

The logic of the routes

Since it's a ridge, the topography is simple to read: there are the high paths, which run along the crest with minimal elevation change and offer the panoramas, and the slope paths, which climb or descend with even considerable gradients connecting the high ground to the entrances from the city. A sensible loop combines the two: you climb from one slope, walk the ridge, descend the other.

What you need

Closed shoes with a lugged sole, always: the clay paths after rain are very slippery, and the word "clay" in this context is not a botanical detail but a warning. Water, because reliable drinking fountains along the routes aren't found everywhere. A hat in summer. And, if you move in the evening hours, a flashlight: twilight under the holm oak grove arrives earlier than in the city.

The non-negotiable rules

You don't leave the marked paths, you don't pick anything (plants, flowers, mushrooms, fossils), you don't light fires, you don't leave trash, dogs must be kept on a leash. These are rules that in a protected area have regulatory force and not just etiquette. And then there's one more rule: you don't play music. The sound of a holm oak grove at sunset is one of the least protected assets of this city.

The wild boar, the fox and the others: urban fauna at Villa Mazzanti

No conversation about Roman protected areas lasts more than 10 minutes without getting to the wild boar. We might as well tackle it head on.

Why there are so many

The wild boar, Sus scrofa, has come back across Europe in recent decades through a convergence of factors: abandonment of the countryside and the resulting re-expansion of the woods, absence of large natural predators over much of the territory, milder winters, and an impressive reproductive capacity (a female can have several litters under favorable conditions). In Rome a decisive local factor is added: the availability of easy food at the urban margins, meaning garbage.

The herds that come down from the peri-urban woods toward the dumpsters are not a natural phenomenon. They are a management phenomenon. A boar that finds every night 100 kilos of food waste 200 meters from the woods has no reason to stay in the woods, and teaches the route to its young. The solution, however unspectacular, starts with closing the containers.

How to behave if you meet one

Calmly. You don't run, you don't shout, you don't photograph up close, you never feed it under any circumstances. You move away slowly keeping your distance and always leaving the animal an escape route, since in the vast majority of cases it only wants to avoid us. There is only one dangerous situation: a female with young, a loose dog, a tight space. Hence yet another reason for the leash.

The other presences

The Roman fox is by now a semi-urban animal, spotted at dawn along neighborhood streets. The porcupine, the largest rodent in Europe, leaves unmistakable traces. Bats come out at twilight and are the best allies against mosquitoes this city has. Among the birds, besides those already mentioned, it's worth keeping an eye out for the bee-eater in the clearings in late spring (it's probably the most colorful bird in Italy) and listening for the tawny owl on winter evenings, whose call is the one we all think of as "the owl".

Via Trionfale, the Francigena and the pilgrims above Villa Mazzanti

The ridge that hosts Villa Mazzanti is crossed by one of the oldest roads of the Roman territory and by one of the great devotional routes of Europe. It's an overlap that deserves to be untangled.

The ancient Via Trionfale

The Trionfale is a road of very ancient origin, which from the Vatican area climbed north in the direction of Veii and Etruscan territory. The name is linked to the tradition of triumphs: it would be the road along which victorious generals coming from the north returned, before crossing the river and following the ceremonial route to the Capitoline. It's a ridge road, like almost all the oldest roads, because ridges are dry, defensible and free of fords.

The Francigena and the last mile

In the Middle Ages the same ridge became one of the routes of arrival in Rome for pilgrims from the north. The itinerary that Archbishop Sigeric of Canterbury described, stage by stage, on his return from his journey to Rome in 990, is the backbone of what we now call Via Francigena. The last stages descend from Tuscia toward Rome, and the entry into the city happens precisely from this quadrant.

The moment of first sight is, as I said, the origin of the name Mons Gaudii. Today the Francigena is a marked and busy path, with thousands of people each year walking at least the last stretch. Whoever arrives on foot from the north still crosses these places, and it's one of the few authentic continuities between medieval and contemporary Rome.

The cross on the mountain

On the ridge there are devotional signs from different periods, crosses and chapels that mark the point of first sight or of the rest stop. It's a very widespread European tradition: wherever a pilgrimage road reaches the point from which the destination is glimpsed, there is a sign. At Santiago it's Monte do Gozo. At Jerusalem, Mount Scopus. At Rome, this ridge.

The Tiber seen from Villa Mazzanti

From the hill the river reads like a map, and this is the occasion to say what the Tiber really is in this stretch.

The bend and the flood

The Tiber enters the city from the north and makes a series of wide bends before narrowing in the Historic Center. At the foot of Monte Mario the river already runs enclosed between the muraglioni, the imposing embankment works built after the disastrous flood of December 1870, a few months after the breach of Porta Pia, almost a baptism for the new capital, which submerged a large part of the center. The muraglioni saved the city from floods and took away its daily relationship with its river. It's one of the great urban planning compromises of modern Rome, and it is still debated.

The river as an ecological corridor

Despite everything, the urban Tiber remains a biological corridor of the first importance. Along the banks you can see gray herons, little egrets, cormorants, kingfishers, yellow-legged gulls that by now nest on the roofs of the center. The riparian vegetation, where it survives, hosts entire communities. Whoever looks from above at Monte Mario sees what from the Lungotevere is invisible: that the river is a continuous green line crossing the gray.

The haze and the light

A practical note for the observer. On humid days the Tiber valley floor holds the haze, which early in the morning forms a low band from which the domes emerge. It's the spectacle that made the Roman views of Corot and the 19th-century landscape painters famous, and from Monte Mario it can still be seen, identical, on the right mornings in October and November.

What to see around Villa Mazzanti

Villa Mazzanti alone doesn't fill a day. Inserted into an itinerary, it fills it very well. Here's how to build it.

The morning: the ridge

Start from the Foro Italico, climb on foot along the slope, arrive in the area of Villa Mazzanti, continue on the ridge toward the top of the reserve and the observatory area. If there are astronomical museum openings on the calendar, this is the time to use them. Indicative time: two or three hours at an easy pace.

The afternoon: the descent

Descent toward the Parco del Pineto on the other slope, crossing the valley, exit toward Valle Aurelia. From there the subway takes you back to the center in 10 minutes. Alternatively, descent toward the Vatican: from the lower part of the ridge you reach Piazza Risorgimento on foot in barely half an hour, and whoever still has energy can close the day under Bernini's colonnade.

The variants

Whoever has a full day and wants to walk can continue north to the Insugherata, where the countryside becomes real. Whoever prefers the urban register can descend toward the Della Vittoria neighborhood and Prati, with its Umbertine architecture and its historic cafes. Whoever has children will find in the Pineto the open spaces and meadows that Monte Mario, wooded and sloping, lacks.

A warning about expectations

I repeat it because it's the most useful thing I can say: Villa Mazzanti is not an attraction with a ticket office, a route and a bookshop. It's an institutional seat inside a park inside a reserve. Whoever arrives thinking of visiting the interiors of a historic villa will be disappointed. Whoever arrives to understand how Rome administers its own nature, and to walk in a wood 20 minutes from St. Peter's, will go home happy.

The other villas of Monte Mario around Villa Mazzanti

The ridge doesn't host only Villa Mazzanti. Over the centuries it has filled with properties of every scale, and knowing them helps place our villa in its social context.

Villa Mellini and the summit

It has already been discussed: it's the villa that gave the hill its name and that today houses the observatory. It occupies the highest point, which in the logic of ridge properties is always the most prestigious, because it dominates everything.

Villa Miani and the season of events

On the slope that looks at the city is Villa Miani, today known mainly as a venue for receptions and conferences. It's the example of a third way in the survival of historic Roman villas, alongside subdivision into lots and public acquisition: reconversion into an events facility. Debatable as much as you like, but it has saved quite a few buildings and quite a few parks that would otherwise have become apartment blocks.

The Zodiaco and the panorama square

The most frequented viewpoint of the ridge is the one Romans call simply the Zodiaco, from the name of the historic venue that overlooks it. It's the spot where the parents' generation brought their sweethearts to look at the city at night, and the custom continues undaunted. It isn't inside the reserve and it is a much more urban setting than Villa Mazzanti, but the view is the same and access is easier.

The healthcare and convent properties

The ridge also hosts clinics, nursing homes and religious institutes that occupy former villas and convents. It's a typical trait of the peripheral Roman hills: good air and distance from the center made them, between the 1800s and 1900s, the natural seat of sanatoriums, hospitals and religious communities. Many of the remaining green areas of Monte Mario owe their survival exactly to these enclosures.

Villa Mazzanti and the paradox of green Rome

There is a fact worth putting on the table, because it contains the whole reason for being of the agency based in this villa.

The greenest capital in Europe, on paper

The City of Rome is, by size, one of the largest in Europe: over 1,200 square kilometers, more than Milan, Turin, Naples, Florence, Bologna, Bari, Genoa, Palermo and Catania put together. Of this surface, a very significant share is not urbanized. Adding up reserves, parks, agricultural estates, archaeological areas and the remaining agro, Rome comes out on paper as the capital with the largest green surface in Europe in absolute terms.

Why the figure is misleading

Because the green per capita actually usable is something else entirely. It's one thing to own 15,000 hectares of reserves. It's another for them to be reachable, signposted, safe, maintained, equipped with services and known. The distance between cadastral green and lived green is the central problem of Roman environmental policy of the last 30 years, and it's exactly the problem being worked on inside Villa Mazzanti.

What would change the game

Continuity of the routes, to begin with: the green crown is fragmented by roads, fences and properties, and stitching it back together requires easements, passages, wildlife underpasses. Then accessibility from the neighborhoods, because a reserve you can reach only by car is a reserve for the few. Then presence, because a frequented area is a de facto protected area: the most effective way to defend an urban wood is to fill it with people who walk in it. It's the reason why writing about Villa Mazzanti is not an archive exercise but, very concretely, a contribution to its conservation.

Villa Mazzanti as a gateway to reading the Roman landscape

There remains the idea that justifies the climb more than any other.

Three landscapes at a glance

From this hill you see at the same time three Romes that are usually studied separately. The ancient and papal Rome, summed up in the dome of St. Peter's and the profile of the Historic Center. The Rome of the monumental 1900s, with the Foro Italico, the obelisk, the Farnesina and the bridge. And the Rome of 20th-century growth, with the residential neighborhoods that climb the slopes and stop, literally, where the woods begin.

The line where the city stops

That line is the most instructive thing about the panorama. It isn't natural: it's administrative. The woods end where the restriction ends, and the built-up area begins where the restriction wasn't there or arrived late. Whoever looks at Monte Mario from above is looking at the map of a century of public decisions, good and bad. It's the kind of reading that makes a walk an education.

Why go back

Because it changes. A monument stays the same, an urban wood doesn't. It changes with the seasons, with maintenance, with the pressure of the city. Villa Mazzanti is one of those places you visit several times in life and that each time tell something different about who we have become in the meantime.

A curiosity about Villa Mazzanti

The curiosity I prefer concerns the ground it rests on. Under the park of Villa Mazzanti, under the holm oaks and the cypresses and the agaves, is the floor of a sea. The blue clays of Monte Mario are marine sediments of the Pliocene and Lower Pleistocene, deposited when the area of present-day Rome was covered with salt water, between about 3 million and a million and a half years ago. Inside those clays there are shells, sea urchins, corals, microscopic foraminifera shells in industrial quantity.

It isn't a museum detail. It's the reason why this hill entered the international geological literature as a reference section, cited in the manuals and visited by generations of scholars. In the 1800s and early 1900s naturalists climbed up here with hammers and canvas bags, and their collections ended up in the Italian paleontological collections. Picture the scene: a professor in a frock coat collecting fossil shells half an hour by carriage from Piazza Venezia.

The funny and vaguely dizzying thing is the overlap of times. Within a radius of a few hundred meters you find a seafloor from 3 million years ago, a ridge road of the Etruscan-Roman age, a Renaissance villa designed by Raphael, a 19th-century fort, an astronomical observatory from the 1930s, a stadium where Serie A is played and the offices of an environmental agency of the 21st century. I don't know many places in the world that stack seven orders of magnitude of time in so little space, and Villa Mazzanti stands exactly in the middle of the stack.

Something nobody tells you about Villa Mazzanti

It isn't a public park. This is the information missing from nine descriptions out of 10 and the one that generates most of the disappointments.

Villa Mazzanti is the operational seat of a public agency. The casino nobile hosts offices, and around it is a park that belongs to those offices and falls within the perimeter of the Monte Mario Nature Reserve. It has no entrance with turnstiles and municipal garden hours, no visitor route, no ticket office. Access is tied to the agency's activity: appointments, initiatives, open days, educational activities, environmental education events. Whoever shows up at random, on a Sunday afternoon, expecting Villa Borghese, may find a gate and nobody to ask.

The right way to approach it, then, is to flip the approach: not "I'm going to visit Villa Mazzanti", but "I'm going to walk in the Monte Mario Reserve, and Villa Mazzanti is its administrative center and its point of reference". The reserve can be freely walked along the paths, the ridge is public, the panorama doesn't ask permission. The villa is the brain of the operation, not the attraction.

I add the practical corollary: if you have a specific interest (an educational visit, a volunteer project, a request for information about one of the reserves of the system, a technical question about a protected area) this is the right place, and contacting them beforehand solves everything. If instead you're looking for a lawn to spread a blanket on, the Parco del Pineto a few hundred meters away does much better for you, and nobody will look at you badly.

The advice I give you for visiting Villa Mazzanti

There is just one piece of advice and it concerns the time: go in the hour and a half before sunset, and go on a day with a north wind, between October and March. Everything else is secondary.

The reason is technical before it is romantic. Monte Mario faces east and southeast: this means the setting sun is at your back and lights the city in front of you head-on. It's the best possible light condition, the one photographers call frontal raking light: volumes stand out, long shadows draw the reliefs, the dome of St. Peter's takes on a color that doesn't exist at noon. With the north wind the air is free of haze and the depth of field reaches the mountains. In summer, with the heat and humidity, the same view is an indistinct gray smear.

The second piece of advice is to climb on foot from below. Take the Lungotevere at the Ponte Duca d'Aosta, cross, skirt the Foro Italico and start climbing. It's 20 or 30 minutes of progressive elevation gain, and it serves two things: to understand physically what it means that Monte Mario is the highest urban elevation of Rome, and to build the view by degrees instead of receiving it all at once from a parking lot. It's exactly the way pilgrims climbed this hill for a thousand years, and the final surprise works better if you've earned it.

Third, and I take responsibility for this: bring real shoes. The reserve's paths are clay, and the wet clay of Monte Mario has the grip of soap. Going down the slope in loafers is an experience we wish on no one.

Another well-known fact, yet rarely mentioned

That Monte Mario is named for Mario Mellini, and not for Gaius Marius, is written in every serious text on Roman place names. And yet try asking around: nine out of 10 people will tell you the hill is dedicated to the consul who reformed the Roman army and defeated the Cimbri and Teutones. It's the most elegant error in the city's place names, because it's plausible: Rome is full of places bearing names of republican figures, and Gaius Marius is famous enough to nominate himself naturally.

But no. The name consolidates in the 1400s and comes from a Roman family, the Mellini, who had extensive properties here and who built the villa later passed to the astronomical observatory. A surname of a patrician family, not a consul. Even earlier, in the Middle Ages, the hill was the Mons Malus, the bad mountain, and for pilgrims the Mons Gaudii, the mountain of joy. Three names, three eras, three completely different ways of looking at the same height: unfavorable for those who had to pass through at night, glorious for those who saw Rome from here for the first time, proprietary for the one who bought the land.

There is a second fact from the same family, equally well known and equally rarely cited: Monte Mario is not the eighth hill of Rome. It isn't for geological reasons (the seven hills are spurs of tuff on the left bank, Monte Mario is a relief of marine sediments on the right bank) and it isn't for historical reasons, because it stood outside the ancient urban perimeter. The right bank, with the Janiculum and the Vatican, is another Rome, and it's useful to remember it while at Villa Mazzanti looking at the seven hills from the outside, as those who arrived looked at them.

The right photo to take at Villa Mazzanti

The right photo is not the wide-field panorama. Everyone takes that one, it always comes out the same and it doesn't hold up against the postcards. The right photo is another, and it is a photo of contrast.

Stand at the edge of the woods, at a point where the branches of the holm oaks frame the opening toward the valley. Use the foliage as a dark frame in the foreground (a branch entering from above, a trunk closing one side) and let the city sit in the hole of light at the center. If you manage to frame the dome of St. Peter's inside that vegetal frame, you have the photograph that sums up the whole story of this place: the woods that survive and the city that presses, one inside the other, in the same image.

Technically you need an exposure measured on the city lights, accepting that the foliage goes into dark silhouette. If you expose for the woods, the sky burns out and the city disappears. Whoever has a recent phone can use portrait mode or HDR, but the most elegant result comes from leaving the frame almost black. The best time is, again, the one before sunset. The second best is the dawn of a humid autumn morning, when the haze rises from the Tiber and the domes float.

A second photo I recommend, much less obvious: the bark. An adult holm oak has a dark gray bark, cracked into small regular plates, which in raking light becomes an extraordinary texture. It's the kind of image nobody takes and that, looked at again months later, brings back the smell of the place much more than a panorama. Add to it, if you can, the hanging pod of a catalpa in winter: it looks like a Japanese engraving and no one will ever guess it's Rome.

Some important events that happened here in history

The hill that hosts Villa Mazzanti has been several times, over the centuries, the place from which the fate of the city below was decided. Not by vocation, but by geography: whoever holds the height holds Rome from the north.

The first great episode is the most famous of late antique Roman history and took place a short distance away, at the foot of the ridge. In 312 AD, near Ponte Milvio, Constantine defeated Maxentius in a battle that changed the religious history of Europe. The troops maneuvered on the plain and on the slopes of this sector, and the outcome (the death of Maxentius in the river, Constantine's entry into the city) opened the way to the Edict of Milan of the following year. Every time you look down from Monte Mario toward the bend of the Tiber, you are looking at the theater of that clash.

The second episode is from 1527, and is the most painful. The imperial troops of Charles V, largely landsknechts, camped on the northern slopes and on the ridge before launching the assault on the Vatican walls on May 6. From here the Sack of Rome began, the catastrophe that closed the Roman Renaissance: months of looting, thousands dead, artworks scattered, Pope Clement VII besieged in Castel Sant'Angelo. Villa Madama, just below, was set on fire on that occasion and was never completed. Whoever walks in this wood today walks on a staging ground of that army.

The third is the post-Unification season. After 1870 the ridge enters the defensive system of the new capital with the construction of the entrenched camp and Forte Braschi, between the end of the 1870s and the early 1890s. In the 1900s come the Foro Italico at the foot of the hill, in the 1930s, and the astronomical observatory on the summit, in the same season. Finally, at the end of the 1990s, the establishment of the regional system of protected areas of the City of Rome and the birth of the agency based right here: the latest act, in order of time, of a story in which this hill has been in turn frontier, encampment, fortification, observatory and reserve.

Who has passed through Villa Mazzanti

We have to be honest about the scale: Villa Mazzanti as a building was not the residence of famous figures, and whoever looked for a list of illustrious guests would come away empty-handed. The ridge it stands on, however, is another matter, because for centuries it was the last stretch of the road to Rome, and practically everyone who arrived in the city from the north passed through there.

Medieval pilgrims passed through, by the tens of thousands, along the route we now call Via Francigena and which Archbishop Sigeric of Canterbury described stage by stage in 990, on his return from his journey to Rome. Grand Tour travelers passed through: whoever came from the Cassia and La Storta crossed this sector and received the first sight of the city, a moment that the travel diaries of the 17th, 18th and 19th centuries describe with an almost religious intensity even when the author was a skeptical Enlightenment man. Montaigne, Goethe, Stendhal, Chateaubriand, Dickens: all left pages on the arrival in Rome from the north, and all crossed this quadrant.

Armies passed through, as we have seen: those of Constantine and Maxentius in 312, the landsknechts in 1527, and in the centuries between every military force that aimed at Rome from the north. In a figurative sense, but not too figurative, the architects of the Renaissance passed through: Raphael designed Villa Madama just below, and Antonio da Sangallo the Younger and Giulio Romano carried on its work site, with Giovanni da Udine on the stuccoes. These are names that belong to the hill even if not to this villa.

And in times close to ours, astronomers passed through. The observatory on the summit has hosted generations of Italian scholars, and the Copernican collections preserved up here tell a piece of the history of European science. I add, without irony, the category that frequents these places today and deserves a place on the list: the officials, technicians, park rangers and volunteers who from the casino nobile of Villa Mazzanti administer 15,000 hectares of protected nature. They won't end up in the textbooks, but they are the ones who decide if these woods will still be here in 50 years.

Quick questions about Villa Mazzanti

Where is Villa Mazzanti

It's on Via Gomenizza, around number 81, on the eastern flank of Monte Mario, where the Della Vittoria neighborhood begins to climb. Below you have the Tiber and the Foro Italico, above the woods. It's a suburban villa with a casino nobile overlooking the city and a park of holm oaks, pines, laurels and cypresses. Today it is the seat of RomaNatura, the regional agency that manages the protected natural areas of Rome.

Can you freely visit Villa Mazzanti

No, it isn't a public park. The casino nobile hosts offices and the park around it belongs to them: there is no ticket office, no visitor route, no municipal garden hours. Access is tied to the agency's activity, meaning appointments, initiatives, open days and educational activities. If you show up at random you may find a closed gate. For a specific visit always ask first. The Monte Mario Reserve around it, on the other hand, can be freely walked along the paths.

How to get to Villa Mazzanti

Access is from Via Gomenizza, above the Foro Italico. On foot you climb from the Lungotevere: you cross the Ponte Duca d'Aosta, skirt the Foro Italico and face a difference in height of about 100 meters, in 20 or 30 minutes. By public transit there are the surface lines that climb from the Mazzini area and from Piazzale Clodio. The nearest subway is line A at Ottaviano, from which you need a transfer. By car parking is difficult.

When is the best time to go to Villa Mazzanti

The recommended time is the hour and a half before sunset, on a day with a north wind between October and March. Monte Mario faces east and southeast, so at that hour the sun is at your back and lights the city in front of you. October and November are the best months for walking. In summer the view is lost in the haze, but under the holm oak grove it's even eight or 10 degrees cooler than on the asphalt.

What you need to walk in the reserve

You need closed shoes with a lugged sole, because the paths are clay and after rain become very slippery. Bring water, since reliable drinking fountains aren't found everywhere, a hat in summer and a flashlight if you're out toward evening. The rules are precise: you don't leave the marked paths, you don't pick anything, you don't light fires and dogs must be kept on a leash. If you meet a wild boar, move away slowly.

What there is to see nearby

The villa alone doesn't fill a day, but within an itinerary it does. In the morning you can climb from the Foro Italico, pass through the villa area and continue on the ridge to the observatory zone, in two or three hours at an easy pace. In the afternoon go down toward the Parco del Pineto and Valle Aurelia, or toward the Vatican and Piazza Risorgimento. With children the Pineto is better suited, because it has the open meadows that Monte Mario lacks.
