Corchiano Gorges

The Corchiano Gorges Natural Monument is a protected area of the Lazio Region that covers 42 hectares in the municipal territory of Corchiano, in the province of Viterbo, and stretches along the course of the Rio Fratta, the stream that runs inside the gorge right below the town's historic center. Management is entrusted to the Municipality of Corchiano, and this explains a large part of how a visit works: there is no park authority with its own offices and a large staff, there is a small town of the Agro Falisco that administers a wooded gorge a few kilometers long and extremely dense with things to see. Inside those 42 hectares you find prehistoric and protohistoric small caves, Faliscan tombs and sunken roads, a Roman bridge, a stretch of Via Amerina, old mills, Faliscan hydraulic works and even a hydroelectric plant that stayed in operation until the early 1960s, which today reads as a piece of industrial archaeology wedged into the greenery. For those arriving from the capital it is one of the shortest and least visited day trips in northern Lazio, and for those touring the province of Viterbo it is the missing link between the farmland on the surface and the carved world running beneath it.

Here you come across the signs, of archaeological value, that peoples left in this place over the course of the ages: inscriptions carved into the tuff walls, vertical cuts tens of meters deep, niches, small channels, burial chambers emptied out and reused as stables. It is not a museum and it is not an equipped trail in the modern sense. It is a damp valley floor with a river in it, where the historical layering shows up without captions. Anyone who arrives expecting an adventure park is left thrown off. Anyone who arrives knowing who the Faliscans are and what the tagliate are comes away convinced of having seen one of the most underrated places in central Italy.

Where the Corchiano Gorges are and how to really get there

Corchiano is in the southern part of the province of Viterbo, in the heart of the area archaeologists call the Agro Falisco: the strip of land between the Tiber to the east and the Cimini Mountains to the west, bounded to the south by the Treja and to the north by the Orte basin. On the surface it looks flat and agricultural, taken up by hazelnut groves, olive groves and vineyards, and yet it turns out to be cut by dozens of deep furrows, invisible until you look over the edge. The gorges are exactly that: narrow, vertical valleys carved by watercourses into the tuff beds deposited by the Cimino and Vico volcanism. The town sits on a cliff naturally defended by ditches, and the natural monument runs along the base of that cliff.

By car from Rome to the Corchiano Gorges

From the capital the natural route is the Flaminia or the A1 motorway with the Magliano Sabina exit, but the route most Romans use goes through the Cassia bis and then the Flaminia toward Civita Castellana, which is the main urban reference point of the area. From Civita Castellana to Corchiano there are a few kilometers of provincial road among fields and hazelnut groves. Those who come instead from the lakes side, that is from Bracciano or from Sutri, enter the Agro Falisco through Nepi and Fabrica di Roma, and in that case it's best to allow a whole day, because along the way you meet things that deserve a stop of their own.

The important point to understand before leaving concerns the internal logistics. The accesses to the natural monument are not concentrated in a single monumental entrance with a ticket office and dedicated parking. They are distributed along the perimeter of the village, and you go down into the gorge from several points of the historic center and its immediate surroundings. This has an advantage and a disadvantage. The advantage is that you park in town, walk a few minutes and you're inside. The disadvantage is that anyone who sets up the visit with the GPS on a generic point of interest risks ending up on a country road without knowing where to go down. The practical solution is to aim for the center of Corchiano, park there and ask in town: the managing body is the Municipality, and in town they know perfectly well how to point out where to go down at that time of year, information that is far from trivial in a valley floor where vegetation and water level change the accessibility season by season.

By Public Transportation and on Foot from the Town

Corchiano has no railway station of its own. The useful stops in the area are along the line that goes up from Rome toward Orte, and the road connection to the small towns of the Agro Falisco is designed for residents, not for Sunday visitors. Translated: without a car the visit is complicated and has to be organized in advance, checking the hours of the regional suburban service, which on holidays is drastically reduced. Those who don't drive have only one sensible way, that is to join an organized excursion departing from Rome or Viterbo, or to rely on a local hiking environmental guide.

Once in town, instead, everything is done on foot. Corchiano is a village of a little over 3,000 inhabitants, the historic center is crossed in a quarter of an hour and the change in elevation between the level of the town and the floor of the gorge is modest in absolute terms: it's a matter of going down a few tens of meters, not of facing an alpine drop. The Club Alpino Italiano route that the regional parks portal maps inside the protected area, coded 136B and titled precisely Forre di Corchiano, is classified as hiking and measures 2.8 kilometers, with practically zero climb and about 15 meters of descent. These are numbers that explain better than any adjective what we are talking about: a short, almost flat walk, where the difficulty is not the altimetry, it's the damp ground and the vegetation.

Where to Park and How to Plan the Day

The guided excursions that over the years have started from here have used as a meeting point the parking lot at Piazza del Bersagliere, in town, and it remains the most convenient reference even for those who come on their own. From there you plan the day in two ways. The first, simpler, involves going down into the gorge, walking the stretch that runs under the cliff up to the Roman bridge and coming back up by one of the sunken roads, closing a loop that brings you back to town. The second, more ambitious, adds the visit of the village, the church of the Madonna del Soccorso and the town's other natural monument, that of Pian Sant'Angelo, which is a WWF Oasis established in 2000 and which shares with the gorges the municipal territory and the geological logic.

What the Forre di Corchiano Really Are: a Forra, Not a Canyon

The word forra creates misunderstandings. Anyone hearing it for the first time thinks of an American canyon, of red walls and a wide river at the bottom. The gorges of tuffaceous central Italy work differently and have to be understood to be appreciated. They are narrow furrows, often only a few meters wide at the bottom, with vertical tuff walls between 10 and 40 meters high, completely closed at the top by vegetation. The feeling is not one of breadth, it's one of a corridor. You walk inside a green tunnel, with the light arriving filtered, the air a few degrees cooler than on the surface and the sound of water bouncing off the walls.

Geology explains it precisely. The regional portal of the protected areas describes the landscape of the area as a set of terraces formed by the eruptive material of the ancient Cimini-Vico volcanic complex, later cut by watercourses, at an average elevation between 150 and 200 meters. In practice, tens of thousands of years ago the volcanoes to the north and west filled this portion of Lazio with pyroclastic deposits that compacted into tuff. Tuff has two properties that matter enormously for the story we are telling: it is soft enough to be cut quickly by running water, and it holds the vertical without collapsing, that is it lets itself be excavated while keeping plumb walls. The first trait produced the gorges. The second allowed the people who lived here to do exactly the same thing the river did, but with iron tools.

The Rio Fratta, a Tributary of the Tiber

The watercourse that carved all this is the Rio Fratta, a tributary of the Tiber. It is not an imposing river and anyone who sees it in August risks underestimating it: in midsummer the flow shrinks and the bed in certain stretches looks almost dry, with isolated pools and gravel. In fall and spring things change, the water runs, and the erosive force that produced the gorge becomes evident again. This seasonal variability is the first practical fact to keep in mind: the Rio Fratta does not behave the same way in April and in August, and neither does the valley floor.

Why the Town Is Right There

A question few people ask, and that instead opens everything up: why an ancient settlement in exactly this spot? The answer is defensive and commercial at once. The cliff on which Corchiano stands is naturally defended by the ditches that surround it and, on the side not protected by water, by an artificial moat. In an age without artillery, a tuff plateau with three sides dropping sheer over a gorge is a free fortress. At the same time the site controlled the transit route that went around the Cimini Mountains from the east, that is the natural corridor between the Tiber valley and inland Etruria, which in Roman times would become the course of Via Amerina.

The Rio Fratta and the Tuff Walls: What You See Going Down into the Gorge

It's worth describing the descent as it presents itself, because it is the part no photograph conveys. You leave the town, take one of the streets that go down toward the ditch and in a few minutes the temperature drops, the noise of traffic disappears and you enter an environment completely different from the one you had behind you. The route that winds under the base of the cliff holding up Corchiano is the heart of the natural monument. In the shade of the ditches grows a dense riparian vegetation, which hides an underground world surprisingly alive, animal and plant together.

The Waterfall and the Retaining Walls

Along the route a small waterfall adds a picturesque note to a landscape that is otherwise dominated by the retaining walls built to protect the cliff. This detail deserves attention because it tells of a constant worry of the inhabitants: a town built on the edge of a gorge lives with the problem of the erosion of its own base. The retaining walls are the engineering answer to that problem, layered over time, and looking at them from below you can read the difference between the ancient stretches and the modern interventions.

The Bottini of the Aqueduct and the Faliscan Hydraulic Works

The technically most fascinating part of the route concerns water governed by people. The trail continues inside the thick of the vegetation and at a certain point you walk inside the bottini of the aqueduct: channels cut into the tuff, with walls ever higher and looming, on which windows open regulated by sluice gates. Those windows and sluice gates testify to the ancient ways of irrigating the gardens and fields below, today largely overgrown with vegetation because they have been abandoned to the intensive cultivation of the flat surfaces.

The Faliscan hydraulic works are one of the identity traits of this whole area of Lazio. The Faliscans, and before them the peoples who occupied these plateaus, had a constant problem: rainwater running over a fissured tuff plateau digs quickly, and if it is not channeled it carries away the arable soil and destabilizes settlements. The answer was a capillary system of drainage tunnels, small channels, dams and diversions that in the Agro Falisco and in nearby southern Etruria counts hundreds of examples. In Corchiano a part of this system is still readable because the gorge preserved it: what on the surface was erased by the plow, under the walls remained.

The Hydroelectric Plant, Industrial Archaeology in the Woods

Inside the boundaries of the natural monument there is also a hydroelectric plant that stayed in operation until the early 1960s. It is the element that surprises most those who don't expect it, because it short-circuits the eras: you walk among Faliscan tombs cut into the tuff and at a certain point a 20th-century industrial structure appears, built with the same logic as all the small Italian river plants of the first half of the century. They took a modest drop of water, channeled it and powered the lighting and the first productive activities of a small district.

A Curiosity About Forre di Corchiano

The most beautiful curiosity of this place has an Etruscan first and last name, and it is carved on the wall of a sunken road. Along the tagliata della Cannara, the cut that crosses the tuff bank and climbs back up between dark walls that hold up cultivated fields and hazelnut groves, you can read the signature of the ancient contractor who wanted to carve his own name on the walls as a lasting memory of his road engineering work. The name is Larth Vel Amies.

Let's stop for a moment on this, because it's enormous and nobody tells it enough. The ancient world left us millions of inscriptions, and the vast majority concern gods, kings, magistrates, well-off dead. Public works almost always carry the name of whoever financed them or of the magistrate under whose term they were carried out, not of whoever physically executed them. Here instead a man who directed an excavation site decided that his name had to remain on the rock he had cut. Not a temple, not a family tomb: a sunken road, a service infrastructure. It is the professional pride of a technician of the first millennium BC, carved on a tuff wall of northern Lazio, and it is still there.

How to Read a Sunken Road

Those who aren't in the trade take a few minutes to understand what they are looking at, so it's useful to give a few keys. A sunken road, or tagliata, is a passage dug vertically into the tuff to overcome a change in level or to cross a plateau without facing a steep climb. The walls are almost plumb and can exceed 10 meters. The width of the floor is, in general, barely enough for a cart. On the walls you can recognize the parallel grooves left by the digging tools, and often you see side channels made to collect rainwater and carry it away, otherwise the passage would become a torrent at the first rain.

The Archaeology of the Forre di Corchiano: Tagliate, Necropolises and Via Amerina

If I had to explain the natural monument in a single sentence, I would say it is a gorge in which history has settled vertically. At the base of the walls open prehistoric and protohistoric small caves, that is shelters used by people even before the Faliscan people existed. Above and around are Faliscan tombs and sunken roads, a Roman bridge, a stretch of Via Amerina, old mills and hydraulic works. This sequence covers something like 3,000 years without a break, and you walk through it in an hour.

The Faliscans, a People Who Spoke Latin and Lived Like Etruscans

It's best to clarify who the Faliscans were, because confusion with the Etruscans is the rule. The Faliscans occupied the strip of territory on the right of the Tiber between Soratte and the Cimini Mountains, with their capital at Falerii, today's Civita Castellana. They spoke an Italic language closely related to Latin, so much so that Faliscan is classified as a dialect of the Latin-Faliscan group and not as an Etruscan language. On the material level, however, their culture appears deeply Etruscanized: urbanism on tuff plateaus defended by gorges, rock necropolises cut into the walls, ceramics and bronzes of Etruscan taste, an alphabet derived from the same stock.

Corchiano belonged to this world and was tied to the capital Falerii Veteres. Its position was particularly advanced and suited to controlling the transit route that went around the Cimini Mountains, and this made it a strategic node. In practice: whoever held Corchiano saw pass anyone who wanted to move between the Tiber valley and inland Etruria without facing the Cimini forest, which for the Romans of the early republican age was a feared and practically impenetrable place.

The Sunken Road of Sant'Egidio and the Rock Necropolis

One of the most beautiful settings is the sepulchral road cut into the tuff that connected the village to its rock necropolis, today known as Via Cava di Sant'Egidio. The concept is the one that holds for all of southern Etruria: the living inhabit the plateau, the dead inhabit the wall of the gorge opposite, and between the two worlds runs a dedicated road, sunk into the tuff. Walking it today means making exactly the trip that funeral processions made 2,500 years ago.

The route presents itself as a corridor of shade flanked by cave rooms and storerooms, that is chambers that were originally sepulchral and that in later centuries were emptied and reused for agricultural needs. At a certain point a staircase carved in the tuff climbs toward a little rock chapel, and at the end of the sunken road you arrive at the church of Sant'Egidio, which keeps a few now-faded paintings and a crucifixion in the apse. This passage from the pagan tomb to the Christian chapel, inside the same cut in the rock, is perhaps the clearest way to understand how the continuity of these landscapes works: nobody ever stopped using them, they only changed their purpose.

The Roman Bridge and Via Amerina

Via Amerina is the Roman road that from Falerii Novi climbed toward Umbria passing through Ameria, today's Amelia, and that in the early Middle Ages became the axis of the Byzantine corridor between Rome and Ravenna, when the other roads were in Lombard hands. A stretch of its course crosses the protected area of Corchiano, and on it there is a Roman bridge that spans the river. Next to the bridge you can see an ingenious irrigation channel, and it is one of the points where hydraulic engineering and road engineering are seen together.

On the dating of the bridge, the indication of the 3rd century AD circulates insistently. I prefer to report it as a widespread local tradition rather than as a certified fact, because the Region's official sheet speaks generically of a Roman bridge without specifying the century. Whoever wants the precise dating has to turn to the specialist archaeological literature or to the competent Soprintendenza. For the visit, the substance doesn't change: it is a Roman structure in tuff masonry that has held up a river crossing at the bottom of a gorge for almost two millennia.

The Church of the Madonna del Soccorso and the Monumental Tombs

Continuing along Via Amerina in the direction of the course of the Fratta you arrive near the church of the Madonna del Soccorso, where the cliff keeps in its walls some large rock tombs with fine architectural and decorative elements. They are the sepulchers of the important families, those with a worked facade, cornices and architectural divisions carved directly in the rock.

The church is Renaissance, dates from the 15th century, is attributed to Giuliano da Sangallo and was declared a national monument in 1902. At the top of the staircase, on the facade, stand two composite pilasters and two peperino columns adorned with coats of arms, rosettes and other decorative elements, with a layout very similar to, or perhaps a direct copy of, that of the Basilica della Madonna della Quercia in Viterbo. Inside are kept fine frescoes, some of which are attributed to Zuccari. Speaking plainly: a Renaissance sanctuary of this level, in any other region of Italy, would have a bus parking lot and a bookshop. Here you reach it by walking along a Roman road at the bottom of a gorge, and on most days of the year you meet no one.

Something Nobody Tells You About Forre di Corchiano

The thing that almost never gets said is about management. The Corchiano Gorges Natural Monument is not run by a regional park authority with a headquarters, park rangers and a visitor center, as happens with the larger reserves of Lazio: the managing body is the Municipality of Corchiano, that is, the administration of a town of just over 3,000 residents. The managing body's seat is in town, and the contacts published by the regional portal are a municipal phone number, a mobile number and a dedicated email address.

This apparently bureaucratic information radically changes the way the visit has to be organized, and anyone who ignores it ends up complaining about the wrong things. It means there are no opening hours for the park in the sense that a museum has them, because the gorge is a valley floor freely accessible from the different points of descent. It also means that maintenance of the passages, cleanup after floods and any temporary closure of a stretch depend on the resources and timing of a small municipality. And above all it means that the right contact before leaving is the Municipality, not a regional call center.

The second thing little talked about is that Corchiano has two natural monuments, not one. The designation of the gorges came in 2008 and is the second to involve this town in the Viterbo area, because the natural monument of Pian Sant'Angelo, managed as a WWF Oasis, had been established there as early as 2000. Two regional protected areas inside the territory of a town of 3,000 residents is a density that very few places in Italy can claim, and the fact that almost nobody knows it says a lot about how tourism communication works in the inland areas.

Frequently asked questions about the Corchiano Gorges

How long does a visit to the Corchiano Gorges take?

The Corchiano Gorges are visited along a mapped hiking route of 2.8 kilometers with minimal elevation change, so the walk alone takes little time. With stops at the caves, the Roman bridge and the sunken road, it's reasonable to count on half a day, which becomes a full day if you add the village and the sanctuary nearby.

Is there an admission fee for the Corchiano Gorges?

The Corchiano Gorges are a natural monument managed directly by the Municipality of Corchiano, a town of just over 3,000 residents, and not by a regional park authority with a visitor center like the larger reserves of Lazio. The exact information on any ticket is not confirmed in the available information, so it's best to check before leaving.

What shoes do you need to walk in the Corchiano Gorges?

To walk in the Corchiano Gorges you need hiking boots with a lugged sole, not sneakers and certainly not sandals. The valley floor is damp almost all year, wet tuff becomes slippery and in several places you walk on rock polished by centuries of passage.

What do you see going down into the Corchiano Gorges?

Going down into the Corchiano Gorges you cross an environment carved by the Rio Fratta, with tuff walls between 10 and 40 meters high and dense vegetation that closes off the sky overhead. Along the route you come across prehistoric small caves, Faliscan tombs and sunken roads, a Roman bridge and a stretch of Via Amerina.

When is the best time to visit the Corchiano Gorges?

The best period to visit the Corchiano Gorges runs from late March to mid-May, when the water has enough flow, the ferns are at their lushest and temperatures on the bottom stay pleasant even on hot days. It is also the season when birds and amphibians are most active along the ditch.

What is the tagliata della Cannara in the Corchiano Gorges?

The tagliata della Cannara is one of the Etruscan cuts dug into the tuff bank of the Corchiano Gorges, between dark walls that hold up cultivated fields and hazelnut groves. On the wall you can read the signature of Larth Vel Amies, the ancient contractor who carved his name to commemorate his road engineering work.

What is there to see near the Corchiano Gorges?

Near the Corchiano Gorges, in the Agro Falisco, you find Civita Castellana with its cliff, the Forte Sangallo and the Cosmatesque portico of the cathedral. Nepi adds its walls, its gorges and the aqueduct, completing an itinerary in the territory crossed by the ancient Via Amerina.

The advice I give you for visiting the Corchiano Gorges

The main advice is just one and it's about shoes. You need hiking boots with a lugged sole, not sneakers and even less sandals. The valley floor is damp almost all year, wet tuff becomes soapy, and in several places you walk on rock polished by centuries of passage. The guided hikes that have started from here over the years listed sportswear, hiking boots and water as recommended gear, noting that poles are useful too. They are sensible suggestions and I agree with them: poles help less with effort and more with balance on slippery stretches.

The second piece of advice concerns company. This is one of the places where a guide completely changes the result of the day. Without someone to explain, an attentive visitor sees a wooded gorge with holes in the rock. With someone explaining, the same gorge becomes a readable sequence of necropolises, tagliate, channeling and agricultural reuse. The excursions in the territory have been led by hiking environmental guides registered in the national register and by licensed tour guides, and it is the best investment you can make here. Those who organize a day with a licensed tour escort, for themselves or for a group, find the service on TourLeaderPro.

How to Set the Order of the Visit

The classic mistake is to start from below and end up tired in town without having seen the village. It's best to do the opposite: half an hour in the historic center before going down, to understand the shape of the cliff and to see the Farnese lily coat of arms that appears in the alleys, and then the descent. This way, when you are on the bottom and look up, you recognize the retaining walls you had just seen from the other side, and the town makes sense as a geological object as well as an urban one.

The Greenery, Fauna and Flora of the Gorge

A fact that explains everything: the only wooded areas of the municipality of Corchiano are precisely the deep valleys carved by the ditches. On the surface the territory has been agricultural for centuries, hazelnuts, olive trees and vines. The woodland survived only where the plow could not reach, that is inside the gorges. What you cross going down into the gorge is therefore not one wood among many. It is the remnant of an environment that elsewhere has been erased, preserved for purely topographical reasons.

The Plants: Two Worlds a Few Meters Apart

The gorge hosts two different kinds of vegetation a few tens of vertical meters apart, and recognizing them is one of the pleasures of the visit. Up high, in the sunniest sectors of the rim, you find thermophilous species: the holm oak, accompanied by manna ash, field maple and European nettle tree. It is the Mediterranean vegetation you expect in a sun-exposed area of northern Lazio.

Going down, the picture changes completely. In the shade of the gorge ferns thrive, and the list is that of damp and shady places par excellence: male fern, hart's-tongue, maidenhair and navelwort. Maidenhair in particular is a plant that grows where water drips from the rock constantly, and seeing it carpet a tuff wall is the clearest sign that that environment keeps its humidity all year. Among the tree species of the valley floor, black alder, white willow, black poplar, elm and white poplar are widespread, that is the classic retinue of the Italian riparian woodland.

The Animals: Notable Presences

The regional portal uses an effective expression, namely that in the small territory of the protected area notable presences are recorded. The first cited is Miller's water shrew, an insectivore tied to clean waters and well-vegetated banks, which works as an indicator of environmental quality. Next to it appear the squirrel, the hazel dormouse, the polecat and the pine marten, that is a community of forest mammals which in an area of 42 hectares wedged between the hazelnut groves can only be explained if the gorge works as a continuous ecological corridor toward other wooded systems.

Among birds, the gorge environment is frequented by the moorhen and the kingfisher, while in the riparian woodland and in that of the adjacent slopes you find wryneck, green woodpecker, great spotted woodpecker, hoopoe, nightingale, wild pigeon and many passerines. The kingfisher gives the greatest satisfaction: a blue line that crosses the watercourse half a meter above the water and vanishes. Anyone who wants to see it has to stay still and quiet for 20 minutes near a pool, a condition that in contemporary tourism is almost subversive.

Among amphibians the Apennine frog and the spectacled salamander are notable. The latter deserves two lines: it is an amphibian endemic to peninsular Italy, of small size, tied to cold and clean watercourses in woodland, and its presence is a true environmental credential, not a decorative one. Seeing it takes luck and attention. Knowing it's there changes the way you place your feet.

Another Well-Known Fact, Yet Rarely Cited

The fact is this: Via Amerina, which crosses the protected area, is not just any Roman road, it is the road that held Byzantine Italy together. Anyone who deals with the early Middle Ages knows it very well, and yet in the tourist presentations of the territory it is dismissed as a stretch of ancient consular road.

The story is this. After the Greek-Gothic war and with the arrival of the Lombards in the peninsula at the end of the 6th century, the territories still in the hands of the Eastern Roman Empire found themselves broken into two pieces: Rome with its duchy to the south, Ravenna with the exarchate to the north. Between the two stretched the Lombard possessions of Tuscia and Spoleto. The great consular roads were cut, and the only practicable link was a narrow corridor that went up the Agro Falisco, crossed southern Umbria and reached the Adriatic coast. The load-bearing axis of that corridor was Via Amerina.

Translated into concrete terms: for about two centuries, everything that passed between the seat of the pope and the Byzantine administrative capital in Italy, that is armies, officials, correspondence, tax collectors, bishops, traveled through this strip of territory. And in this strip of territory is the stretch that crosses the Forre di Corchiano. Walking on the paving stones inside the gorge means walking on one of the few arteries left open in a fragmented Italy.

The Right Photo to Take at Forre di Corchiano

The right photo here is not the panorama and it is not the waterfall. It's the vertical wall with a human figure in it.

The reason is technical. A gorge doesn't photograph well from above, because from above you see only a strip of green treetops and you can't tell that below there is a 30-meter cut. And it doesn't photograph well in close-up, because without a point of comparison the tuff looks like any rock wall. The photo that works is taken from the bottom, putting a person standing against the wall and framing vertically until you catch the sky between the treetops. At that point the scale reads by itself, and whoever looks understands instantly that that crack in the world is as tall as a 10-story building.

Settings and Timing

The biggest difficulty is contrast. The bottom of the gorge is in deep shade and the slit of sky above is very bright, which means a difference of several stops within the same frame. With a phone it's best to tap the screen on the shaded wall and accept that the sky will blow out: a white sky is preferable to a black wall. With a serious camera you work in raw and recover in post, or you shoot two exposures and blend them. A tripod helps because the sensitivities required at the bottom are high.

The best time of day is when the sun is high enough to slip a few blades of light into the gorge, that is around noon, which is the exact opposite of the general rule of landscape photography. In the gorges low-angle light doesn't get in, so the golden hour is useless and in fact delivers a completely dead valley floor. The best season is late fall or late winter, when the trees have fewer leaves, light comes down more easily and the water has a decent flow.

The Other Subject Worth Shooting

The other subject not to be missed is the signature carved in the sunken road of the Cannara. It should be photographed at an angle, with side light, otherwise the carving flattens and becomes unreadable: a flashlight held to the side gives much better results than a frontal flash.

Some Important Events That Took Place Here in History

I list the passages that have left a readable mark on the ground, in chronological order, honestly distinguishing documented facts from debated attributions.

From Prehistory to the Faliscans

The first human presence in the area is attested by the prehistoric and protohistoric small caves that open at the base of the walls. Then, in the first millennium BC, the Faliscan settlement takes shape on the plateau, with the rock necropolis on the walls opposite and the system of sunken roads that connects the two worlds. The archaeological documentation of this settlement is significant in the framework of the northern Agro Falisco, but the ancient name of the center remains unknown: the identification with Fescennium, proposed on the basis of literary sources, finds no confirmation in the finds. It is a rare case of an important and anonymous site.

The Roman Conquest and Via Amerina

In 241 BC Rome destroys Falerii Veteres, today's Civita Castellana, and deports the population to the new Falerii Novi, on the plain and without natural defenses. This is the moment when Faliscan autonomy ends. From then on the territory is reorganized according to Roman logic, and Via Amerina becomes the load-bearing axis of the link toward Umbria. The Roman bridge that you cross today inside the gorge belongs to this phase of infrastructural reorganization.

The Byzantine Corridor

Between the 6th and 8th centuries AD Via Amerina becomes, as mentioned, the backbone of the corridor that kept the Duchy of Rome and the Exarchate of Ravenna connected through territories that were otherwise Lombard. For the territory of Corchiano it means remaining on a strategic route in an age when almost all the rest of central Italy was fragmenting.

The Middle Ages, the Farnese and the Lily

The late Middle Ages leave the village a history dense with chivalric episodes, and the Renaissance hands it over to the rule of the Farnese family, the house that from Farnese and the Tuscia rises to the papacy with Paul III and to the duchy of Parma and Piacenza. The family's coat of arms, the lily, still appears frequently today in the alleys of Corchiano's historic center, and it is the most immediate way to read in stone to whom this territory belonged in the 16th century. Whoever wants to understand what Farnese power meant over this portion of Lazio has to see the Palazzo Farnese in Caprarola, less than an hour from here.

The 20th Century and Protection

In 1902 the church of the Madonna del Soccorso is declared a national monument. In the first half of the 20th century the hydroelectric plant on the Fratta comes into operation, and it remains active until the early 1960s. In 2000 the Lazio Region establishes the natural monument of Pian Sant’Angelo, in the same municipality. Finally, the Forre di Corchiano Natural Monument is established by Decree of the President of the Lazio Region of October 30, 2008, number 635, published in the Official Bulletin of the Region of November 28, 2008, number 44, and later amended and supplemented by Resolution of the Regional Council of October 2, 2013, number 92, published in the Official Bulletin of January 30, 2014, number 9. They are boring dates to read, but they are the ones that kept this gorge from ending up like so many other Lazio gorges used as dumps or erased by agricultural reclamation.

Who Passed Through Forre di Corchiano

The list of famous figures tied to this place is short and has to be told without inflating it, because the Agro Falisco is not the Grand Tour and anyone who claims otherwise is selling smoke.

The first name is that of Larth Vel Amies, the contractor who signed his work on the wall of the sunken road of the Cannara. He was not a king and he was not a famous artist, he was a technician, and for once we have the name of whoever actually built something instead of the name of whoever paid for it. In the history of ancient Italian engineering it is a rarity and to me he seems the most interesting figure on the whole list.

The second name is that of Giuliano da Sangallo, to whom the church of the Madonna del Soccorso is attributed. The attribution should be taken for what it is, that is an attribution consolidated in the local literature and repeated in the official sheets, not an autograph signature on a contract. Sangallo worked in this portion of central Italy and the architectural language of the facade is consistent with his circle. Whoever wants to be cautious will speak of the Sangallo milieu.

The fourth passage has no single name and is the most important of all: the popes, the imperial legates, the exarchs and the Byzantine officials who between the 6th and 8th centuries traveled Via Amerina between Rome and Ravenna. We don't know which of them stopped exactly here, and I won't write it, but we know that this was the route, and that whoever went from one capital to the other passed through here. For a 42-hectare gorge in northern Lazio it is a more than dignified résumé.

When to Go to the Forre di Corchiano and When to Avoid Them

The season changes this place more than it changes any other destination in Lazio, so it's worth being precise.

Spring, the Best Season

From late March to mid-May the gorge is at its best: the water has sufficient flow, the ferns are at their most luxuriant, the birds sing, the amphibians are active and the temperatures on the bottom stay pleasant even on hot days. It is also the period when the contrast between the sunny plateau and the cool valley floor is best perceived. The only price to pay: after heavy rain the ground becomes muddy and certain passages near the water are slippery.

Summer, with a Few Warnings

In July and August the gorge remains a real thermal refuge, and it is one of the few places in northern Lazio where you walk with relief at noon in August. On the other hand the flow of the Fratta drops, mosquitoes abound and the vegetation closes many views. Those who come in summer hoping for rushing waterfalls are disappointed. Those who come looking for shade and archaeology are satisfied. I repeat the point: the pools are not declared swimmable by any official source, and this is not a trip for swimsuits.

Fall, the Photographers' Season

October and November bring two enormous advantages: the first rains put water back in the stream and the falling of the leaves opens the plant canopy, letting light down to the bottom of the gorge. The riparian woodland of alder, poplar and willow turns intense yellows. It is the moment when the gorge is best photographed and best read, because the walls become visible again.

Winter, for Those Who Know What They're Doing

From December to February the valley floor is cold, damp and dark early. Floods can make certain stretches impassable or dangerous, and after episodes of intense rain the sensible thing is to postpone and check with the Municipality. On the other hand, on clear January days, without leaves and without anyone, the gorge shows its geological structure with a clarity it doesn't have in other seasons. It's worth it for those with experience, adequate equipment and no hurry.

What Is Around the Forre di Corchiano

The great advantage of this area is density: within a few kilometers there is a concentration of villages, protected areas and archaeological sites that elsewhere would be enough to fill an entire region.

The Agro Falisco and Via Amerina

Civita Castellana is the obligatory reference point, with its cliff, the Forte Sangallo and the Cosmatesque portico of the cathedral. Nepi adds the walls, the gorges and the aqueduct, and nearby it keeps the Solfatara di Nepi and Monte Calderone. Castel Sant’Elia can't be skipped for the early medieval basilica overlooking the gorge. Completing the picture are Fabrica di Roma, Faleria, Vasanello, Orte with its underground city, Bassano in Teverina and, on the Roman side of the Tiber, Civitella San Paolo and Filacciano.

The Other Gorges and the Nearby Protected Areas

Those who get passionate about this kind of landscape have plenty to continue with. The Treja Valley Park offers the same gorges on a larger scale, with the Monte Gelato waterfall and the village of Calcata perched on a spur of tuff. The municipality's other natural monument, Pian Sant’Angelo, is a few minutes away. Toward the Tiber you find the Nazzano Tevere Farfa Nature Reserve, with the bird observatory on the bend of the river, and farther east the Farfa Gorges.

The Lakes and the Cimini

To the west the landscape changes and becomes volcanic. Lake Vico with its nature reserve is the least built-up lake in Lazio, and around it are Caprarola with its pentagonal palace, Ronciglione, Vignanello, Vallerano, Soriano nel Cimino with the abandoned village of Chia, Capranica and Vetralla. Sutri with its archaeological park and the amphitheater carved into the tuff is the stop that goes best with Corchiano, because it tells the same relationship between people and rock. Not far away are the Oriolo Romano Beech Forest and the Mola di Oriolo Romano.

Heading down toward Rome you enter the district of Lake Bracciano and the Bracciano Martignano Park, with Bracciano and its Odescalchi castle, Trevignano Romano and Anguillara Sabazia. Toward the provincial capital, finally, Viterbo with the medieval San Pellegrino district and, in the surroundings, Villa Lante in Bagnaia.

Quick Questions About Forre di Corchiano

How long does the visit to the Forre di Corchiano take?

The mapped hiking route inside the protected area measures 2.8 kilometers with minimal change in elevation, so in terms of the walk alone we are talking about little. With stops, the caves, the bridge and the sunken road it is reasonable to allow half a day, and a whole day if you add the village and the sanctuary.

Do you pay a ticket?

The natural monument is a freely accessible regional protected area, not a site with limited entry. The guided visits organized by guides and associations naturally have their own cost, which varies from operator to operator.

Who manages the natural monument?

The managing body is the Municipality of Corchiano, in the province of Viterbo. For updated information on access, temporary closures and visits it's best to contact the Municipality directly, which publishes its telephone and email contacts on the regional portal of the protected areas.

How big is the protected area?

The extent is 42 hectares, entirely within the municipal territory of Corchiano, territorial district of Viterbo.

Is it suitable for children?

Yes, from six or seven years old and up, with proper shoes and supervision near the water. It is not suitable for strollers or for those with mobility difficulties, because the ground is uneven and in several places slippery.

What is the difference between the Forre di Corchiano and Pian Sant’Angelo?

They are two distinct natural monuments of the same municipality. The Forre protect the stretch of gorge along the Rio Fratta with its tuff walls and its archaeological layering. Pian Sant’Angelo, established in 2000 and managed as a WWF Oasis, protects a contiguous area with its own characteristics. Visiting both on the same day is entirely feasible.

Can you swim in the pools of the Rio Fratta?

No official source declares the stream's pools swimmable. They are not supervised and their depth and flow change with the season. The prudent answer is no.

The Forre di Corchiano are the right place for those who have understood that the interesting Lazio is not that of isolated monuments but that of layered landscapes. Here, in a little over two kilometers of valley floor, you cross a volcanic gorge, a rock necropolis, a Roman road, an ancient bridge, a pre-Roman irrigation system and a disused power plant, with maidenhair on the walls and the kingfisher on the water. Those looking for an attraction with a ticket office and a marked route will leave puzzled. Those looking for a place to read will come back.
