Gasometro di Roma

The Gasometro of Rome cannot be visited freely: it sits inside the complex of the former San Paolo gasworks, owned by Eni, with the event entrance at Via del Commercio 9-11, 00154 Rome. You get inside only on Gazometro Aperto days, guided visits that Eni organizes with the FAI by reservation, and during events such as Maker Faire Rome. From outside you can look at it for free, at any hour, from the bridges and the banks of the Tiber.

For Romans it is not the Gasometro, it is the Gazometro, with a z, and that is what the City, Eni and the FAI call it too. It is the steel cage almost 90 meters high that you see from Via Ostiense, from the Lungotevere, from Testaccio and from Marconi. A gas container that has been empty for over 60 years and has become the symbol of a whole neighborhood, without anyone having decided it at a desk.

The practical information comes from the official sources: the Gazometro Aperto website and its calendar, the pages of the FAI, the City of Rome, Eni and the Chamber of Commerce that organizes Maker Faire. The dates of the guided openings change every year and sell out early, so before you set out always check the updated calendar or write to the initiative's secretariat.

Where it is and what you really see

The complex occupies the left bank of the Tiber between the Ponte dell'Industria and the Ponte della Scienza, behind Via Ostiense, in the stretch where the Ostiense district stops being consolidated city and becomes riverfront. The area stated by Eni and the FAI in 2024 exceeds 12 hectares. Inside are the large gasometer, three smaller gasometers, masonry sheds from the early twentieth century and offices.

The large gasometer is a cylinder of dark-painted steel beams, about 89 meters high and 63 wide. Today it is an empty cage: inside there is no longer the tank that rose and fell according to the amount of gas stored. Precisely because it is empty you read it like a drawing, a net of verticals and horizontals that changes look depending on the light and the point you view it from.

Next to it you notice the three smaller gasometers, lower, a quarter of a century older and with a lighter structure. They are the ones that, put together with the large one, give the area the profile you recognize from afar. Those arriving on foot from Via del Commercio, instead, see the masonry sheds first, now used by offices, business schools and event spaces.

From outside you grasp the size well and little else. The perimeter wall and the fences take away the view at street level over much of the complex, and the gasometer appears above the roofs or at the end of the avenues. To understand the layout as a whole you need one of two things: go up on the Ponte della Scienza, or book a guided visit on the days when the area opens.

What you do not see: the upper levels of the structure, because the gasometer is never climbed under any circumstances, and the parts of the complex occupied by offices and companies. Whoever offers photos from the top or alternative entrances is telling you something that does not exist. The gasometer is enjoyed from below and from afar, and that is its strength, as with any industrial architecture designed to work and not to be visited.

Can you go in? Current status and openings

The short answer is no, except for scheduled exceptions. The area is private, fenced and works as a district of companies and training owned by Eni. It has no public opening hours, no ticket office, no caretaker who lets you in for a look around. Showing up at the gate without a reservation on an ordinary day means finding a controlled entrance and no visit possible.

The exceptions have a precise name. Gazometro Aperto is the program of guided visits launched by Eni with the FAI in 2024: in that first edition five Sundays between June and November, free and with mandatory reservation, plus special visits during the big events. In 2025 the formula continued, still free according to the specialist press, with a stated duration of an hour and 40 minutes.

The 2026 calendar published on the official Gazometro Aperto site lists nine days: May 16 and 17, May 23 and 24, June 6 and 7, September 5 and 6, September 13. As of the verification date all show registrations closed. The cost for the 2026 edition is not indicated on the calendar page. To find out if other dates are planned the only published channel is the secretariat, segreteria@enigazometroaperto.it.

The FAI has also organized visits reserved for its members, for example on Sunday, November 16, 2025, with meeting point at Via del Commercio 11 and shifts from 09:30 to 16:25. For these openings the contact is the FAI Delegation of Rome, telephone 06 6879376, roma@delegazionefai.fondoambiente.it. In November 2025 a special visit tied to the Jubilee cultural calendar was added, with a maximum of 45 people per shift.

The second way in is the events. Maker Faire Rome, the innovation fair organized by the Rome Chamber of Commerce through Innova Camera, has been held at the Gazometro since 2021. The 2026 edition is announced from October 23 to 25, from 10:00 to 19:00, with tickets sold on the official Maker Faire Rome site. On those days you walk among sheds and gasometers, even if the attention goes to the stands.

Then there is Videocittà, the festival of vision and digital culture that Eni has hosted in the area since 2022, with light installations projected also on the structure of the gasometer. Dates, programs and access arrangements change from year to year and must be checked on the organizers' channels. None of these occasions takes you to the top, and none lets you wander alone wherever you want.

A curiosity about the Gasometro of Rome

The name is wrong. A gasometer, strictly speaking, should measure gas, and this one did not measure it at all: it stored it. It was a buffer tank, which filled at night, when consumption dropped, and emptied by day and in the evening, when the city lit its street lamps and stoves. The term comes from an eighteenth-century laboratory instrument and stuck to industrial plants out of pure habit.

Hence the second curiosity, the one about the z. The City, Eni, the FAI and Wikipedia write Gazometro. The Italian dictionary accepts both forms, but in Rome it is said with the z and that's it, and it is the form used by the institutions and the owner of the area too. If you search for it online with the s you find fewer results and more confusion. With the z you find everything.

Third curiosity, the most concrete one. The cage you see today was only the outer shell. Inside moved the real tank, which rose when gas came in and fell when it went out. Looking at the gasometer from afar, the Romans of the time could tell at a glance how much gas the city had in reserve. An urban indicator 90 meters tall, readable from kilometers away, that nobody had designed as such.

When production ceased, in the 1960s, the inner tank was dismantled and the cage stayed. This choice, for economic reasons more than cultural ones, saved the gasometer: an empty structure weighs little on the budget, raises no gas-related safety problems and costs less to keep standing than to demolish. It went this way in many European cities, and Rome was no exception.

Something nobody tells you about the Gasometro of Rome

What everyone calls the Gasometro, in the singular, is actually a system of four. The three smaller ones are the oldest, built between 1910 and 1912, and they were the ones that ran the works for a quarter of a century before the large one arrived. Two had a capacity of 25,000 cubic meters each, the third 60,000. The large one, alone, held 200,000.

The second point nobody tells concerns the dates. The FAI gives the start of the San Paolo works as 1908, Wikipedia places the design in 1909, the historical route prepared for the 150 years of Roma Capitale speaks of works built in 1910. The sources do not agree, and the reason is simple: a plant of that size has a year of design, a year of construction and a year of firing up, and everyone cites the one they prefer.

Third point, less known and more interesting. The large gasometer is not a Roman work: the sources name as builders Ansaldo of Genoa and Klonne of Dortmund, that is, an Italian firm and a German one specialized precisely in gas tanks. The three smaller ones, 30 years earlier, had been entrusted to a London firm. The whole plant tells of the technological dependence of early-century Italy on northern European industry.

Last point, on the dimensions. Wikipedia gives a height of 89.10 meters and a diameter of 63, the City says almost 90 and 63, a 2025 Artribune article writes 90 and 60. On the diameter the sources do not agree. On the height the difference is one meter. Whoever tells you with confidence that the gasometer is exactly 90 meters tall is rounding, and that's fine, but it is a rounding.

Let's add something practical. The gasometer is presented as the largest in Europe, and it is a line the City itself reports in reference to its entering service in 1937. Today that line circulates in the present tense, as if it were still true. It is not, in any useful sense: the plant has been off for decades and comparison with today's industrial tanks has no meaning. It remains a historic record, not a current one.

The numbers of the large gasometer and the three smaller ones

The data that follow come from the Wikipedia entry and from the City of Rome entry published on April 5, 2024, which coincide on almost everything. The large gasometer was built between 1935 and 1937 and entered service in 1937. The capacity was 200,000 cubic meters of gas. The iron used, according to the City, weighs about 3,000 tons, the weight of a merchant ship set down on the bank of the river.

The riverbank ground could not bear a load like that without help. That is why the structure rests on over 1,500 piles driven into the soil, 1,551 according to Wikipedia, which lined up would cover 36 kilometers. It is the part nobody sees and that explains why the gasometer is still upright after 90 years next to a river that floods. The foundations are the real technical masterpiece of the plant.

The three smaller gasometers, built between 1910 and 1912, had much smaller capacities: 25,000 cubic meters for the two smaller ones, 60,000 for the third. Put together they came to a little more than half of what the large one held alone. It is a measure of Rome's growth between the wars: in 25 years the demand for gas had grown to the point of requiring a tank that doubled the whole existing capacity.

The decommissioning comes in the 1960s. The City writes from about 1960, other sources speak more generically of that decade, and the cause given is the same: the spread of methane, which arrived in the city through the grid and no longer had to be produced from coal and stored on site. From 1967, again according to Wikipedia, ownership passes to Eni through Snam and Italgas.

A caution on the use of these numbers. They are design and capacity data, not measurements taken on site in recent years, and the sources report them with different roundings. If you need them for a job, a thesis or a panel, cite them giving the source and the year. For a visit or a chat it is enough to remember three figures: 90 meters, 63 in diameter, 200,000 cubic meters.

My advice for visiting the Gasometro of Rome

Go at sunset and look at it from the Ponte della Scienza, the pedestrian and bicycle bridge that starts from Riva Ostiense exactly level with the gasometer and crosses the Tiber toward Marconi. Put the gasometer behind you and the sun in front, then turn around. In half an hour the cage goes from gray to black against the light on an orange sky, and you understand why directors and photographers keep coming back here. It costs nothing and you don't need to book.

If you want to go in, sign up for the newsletter or keep an eye on the Gazometro Aperto site from the end of winter. In 2026 the first dates were in mid-May and by the end of September they all showed as closed. The visits are free in the documented editions and the places go fast: whoever waits to read the news in the papers usually finds the calendar already full.

A contrarian position, stated plainly: the inside visit is overrated. It is well done, well told, but it takes you into a corporate district with restored sheds and shows you the gasometer from below, too close to take in its shape. The gasometer does its best from a distance, between 200 meters and a kilometer. If you have to choose between the visit and a sunset on the bridge, choose the bridge.

Wear comfortable shoes. Riva Ostiense and the Tiber quays have uneven stretches, and if you go down to river level you find mud after the rains. On the bridge in summer it is hot, because there is not a thread of shade, and in winter the wind blows. Bring water: on the stretch of bank next to the gasometer there are no kiosks or fountains within reach, and the bars are all on Via Ostiense.

For guided visits, arrive 15 minutes early: the FAI expressly asks for this for its openings, and the check at the entrance of a corporate area takes time. Keep your booking confirmation at hand. During events the FAI states that it takes photos and videos for its channels and that anyone who does not want to be filmed can tell the staff.

Last piece of advice, for those coming from outside Rome. Don't build a day around the gasometer alone, because from outside you see it in an hour and inside, on the good days, you need less than two. Put it in a tour of Ostiense that includes the Centrale Montemartini, the street art of Ostiense and a piece of Testaccio. I talk about it further on.

Where to look at it well, and legally

The first spot is the Ponte della Scienza, named after Rita Levi Montalcini. Opened to traffic on May 29, 2014 and inaugurated on July 8 of the same year, it is 147 meters long and reserved for pedestrians and bicycles. It connects Riva Ostiense, level with the gasometer, to the Lungotevere Vittorio Gassman, where the Teatro India is. From mid-bridge you have the whole gasometer, unobstructed, with the river below.

The second spot is the Ponte dell'Industria, which everyone in Rome calls Ponte di Ferro. Built in 1862-63 under Pius IX, 130 meters long, it was devastated by a fire on October 2, 2021. After a work costing 18 million euros it reopened in March 2025 with a widened roadway, a pedestrian walkway and a bike path. From there the gasometer appears on the diagonal, behind the vegetation of the bank.

The third spot is the Lungotevere Vittorio Gassman, on the Marconi bank. Walking along the sidewalk between the Ponte della Scienza and the Ponte dell'Industria you have the gasometer in front of you, across the water, and the chance to choose your framing at leisure. It is the frontal view, the postcard one, and in the evening it works well also because the gasometer area is lit during events.

The fourth spot is the city itself. The gasometer shows up at the end of Via del Porto Fluviale, above the roofs of Via del Commercio, behind the signs of Via Ostiense, from the hill of Garbatella. The nice thing is just this: you don't look for it, you find it. In Rome few twentieth-century buildings have this ability to appear by surprise at the end of any street.

Where not to go. Don't climb over fences, don't enter construction areas, don't go down onto quays where the gates are closed, don't try to photograph from inside private courtyards or the sheds. The gasometer is private property, it is guarded, and there are companies at work every day. All the best views are from public ground, and there is no reason to risk a report to the police for a photo.

A last note on the Riva Ostiense area, the strip between the Ponte di Ferro, the gasometer, the former Italgas and the river. According to a LifeGate article of March 2026 it is still little developed and is the subject of an urban park project of 2,000 square meters, with spaces for play, sport and street art. As of the verification date it is a project, not an open construction site.

Another well-known fact, yet rarely cited

The gasometer is the child of a precise political choice. It was the administration of Mayor Ernesto Nathan, in office from 1907 to 1913, that approved the 1909 Master Plan, which designated this stretch of Via Ostiense as an industrial zone. In a few years came the river port, inaugurated in 1912, the Montemartini power plant, also from 1912, the Mercati Generali and the gasworks.

Everyone knows that Ostiense was Rome's industrial district. Few remember that it was the only one, and that it did not last long. Rome never became a city of factories like Milan or Turin, and this short season, between 1909 and the post-war period, left a handful of buildings that today seem out of proportion with the rest of the urban fabric. The gasometer is the most visible of all.

The second rarely cited fact concerns the Mercati Generali, the large complex between Via Ostiense and the gasometer. The sources do not agree on the date of construction: LifeGate gives 1913, the Roma Capitale route the years 1922-27. They stayed active until 2002. In 2005 Rem Koolhaas's studio won the call for the transformation of the area, which is however still unresolved. 20 years later, the gates are still the same.

The third fact is that the gasometer became a symbol precisely when it stopped being useful. As long as it worked it was an ugly, bulky plant, the kind you put far from homes. After it was shut down, with the city grown up around it, it became the hallmark of Ostiense. The City, in its 2024 entry, calls it the icon of the district. The passage from industrial nuisance to symbol took half a century.

The right photo to take at the Gasometro of Rome

The right photo is taken from the Lungotevere Vittorio Gassman, on the other side of the river, 15 minutes after sunset. Stand level with the Ponte della Scienza, use a normal focal length or a light telephoto, and keep the Tiber in the lower part of the frame. The still-light sky sets off the black cage, and the reflection in the water doubles the structure. In landscape orientation, because the reflection needs space.

The second photo is taken from the Ponte della Scienza, looking toward Riva Ostiense. Here you use the lines of the bridge as a guide: the parapet and the walkway carry the eye toward the gasometer. Since 2024 the bridge also has an extra color, because the artist Giulio Vesprini painted its deck with the work Upside Down, 1,000 square meters of the colors of the seasons, which works as a foreground in photos.

The third photo is for those who love geometry. Stand near the base, on the public sidewalk of Riva Ostiense, and point upward. With a wide angle the cage becomes a spiderweb of beams converging toward the sky. It is an image seen a lot on social media, but it always works, especially under overcast sky, because uniform clouds give a clean background and the structure comes out without hard shadows.

Avoid summer noon. With the sun high the cage flattens, the beams lose depth and the sky burns out. Avoid also the photo from Via Ostiense in the middle of traffic, with light poles, billboards and traffic lights in front: it is the spot where everyone stops because it is the most convenient, and it is the worst. 200 meters farther on, toward the river, you already have another photo.

On the evenings of Videocittà and on the other occasions when Eni lights the complex, the gasometer changes completely. In 2026 the company presented light installations called In Lympha and UNDA. If you happen to be there on one of those evenings, the photo from the bridge is worth the trip by itself. Hold the camera steady on the parapet, because with artificial light you need long exposures and a tripod is not always welcome on the crowded bridge.

How to get there

By metro take line B to Piramide. According to the directions published by Maker Faire Rome, from the stop to the Gazometro it is about a kilometer, 10 or 15 minutes on foot. Those leaving from Termini Station reach Piramide in a few minutes with no changes. The exit brings you out on Piazzale Ostiense, in front of the Pyramid of Cestius and Porta San Paolo.

By train you get off at Roma Ostiense station, also about a kilometer away, exiting onto Piazzale 12 Ottobre 1942. From Fiumicino the connection is direct: the FL1 regional train reaches Ostiense in about 30 minutes, with the frequencies given by Maker Faire Rome of one train every 15 minutes on weekdays and every 30 on holidays. For those arriving by air it is the simplest solution.

By bus, ATAC lines 23 and 769 stop on Via Ostiense at the Ostiense/Mercati Generali stop, the closest to Via del Commercio entrance. Check the schedules the day before, because in the evening and on holidays frequencies drop. By taxi the number given is that of the municipal switchboard, 060609. To get around the city it is also worth reading our guide on getting around Rome.

By bicycle the gasometer is a natural stop. The Ponte della Scienza and the new Ponte dell'Industria have bike paths, and the banks of the Tiber let you arrive from Testaccio or Marconi avoiding the traffic of Via Ostiense. You will find some route ideas on the page about Rome by bike. Just watch out for the stretches of quay closed after the river's floods.

By car forget it, especially on the days of Maker Faire and the other events. The area has street parking contested among residents, Roma Tre students and offices, and the flow of the events saturates it. The organizers do not publish a parking lot dedicated to the public. If you really must come by car, leave it farther away and do the last stretch on foot or by metro.

Some important events that happened here in history

Between 1908 and 1910, according to the sources, the Società Anglo-Romana per l'illuminazione di Roma col gas starts the new San Paolo works on the bank of the Tiber. Between 1910 and 1912 the three smaller gasometers are built. It is the phase in which the Nathan administration builds the industrial Ostiense, and the gasworks is one of the pillars, alongside the river port and the power plant.

In 1935 the building site of the large gasometer starts, entrusted to Ansaldo and Klonne of Dortmund. In 1937 it enters service, with a capacity of 200,000 cubic meters and, according to the City, the record of largest tank in Europe. These are the same years in which Rome builds the Città Universitaria of the Sapienza and prepares the world's fair that will give rise to EUR.

In the 1960s gas production from coal stops, with the arrival of methane on the grid. The inner tank is dismantled and the cage remains. From 1967 the property belongs to Eni, passed through Snam and Italgas. For decades the area stays largely idle, with few offices active: in 2017 the local press described it as blocked above all by the costs of cleaning up the soil.

In 2006, during the Notte Bianca, the gasometer becomes the Luxometro, covered with over a million LED bulbs. In March 2020 it is lit with the tricolor in memory of the victims of Covid. In the same period the international press begins to cite Ostiense among Europe's emerging neighborhoods. For those who had always lived there, a confirmation from outside of something they already knew.

From 2020 Eni fills the area with activities: the Joule business school in 2020, the ZERO accelerator in 2021, the Eni 2050 Lab space in 2022. From 2021 the complex hosts Maker Faire Rome, from 2022 the Videocittà festival. On May 17, 2023 ROAD, Rome Advanced District, is born, with partners such as Gruppo FS, Acea, Bridgestone, Cisco and Autostrade. In 2024 the Gazometro Aperto visits with the FAI begin.

Meanwhile the surroundings change. On October 2, 2021 a fire devastates the Ponte dell'Industria, which reopens in March 2025 after works costing 18 million euros. In 2024 Giulio Vesprini paints the deck of the Ponte della Scienza. In spring 2026 LifeGate reports as just inaugurated the Dots route, which connects Piazzale Ostiense with Via del Porto Fluviale among urban art and points of interest in the district.

Who passed through the Gasometro of Rome

Ernesto Nathan, mayor of Rome from 1907 to 1913, did not see the large gasometer, but without him the gasometer would not exist. His 1909 Master Plan decided that Rome must have an industrial district and that it must be here, between Via Ostiense and the river. He is the mayor historiography remembers for the schools and for the municipal electric company, less for this urban planning choice.

Pier Paolo Pasolini used it as a backdrop in Accattone, in 1961, in the years when the plant was being decommissioned. The City lists him first among the directors who chose the gasometer. Pasolini looked for the real peripheries, the places where Rome stopped being a monument, and the Ostiense of that time, among factories, river and shacks, answered that search perfectly.

Carlo Verdone framed it in Troppo forte, in 1986. Ferzan Özpetek made it almost a character in Le fate ignoranti, in 2001, a film that changed the perception of the district more than any urban plan. Michele Placido filmed it in Romanzo criminale, in 2005. In 2023 the Måneskin shot the video for Honey here. All titles listed by the City in its entry.

The engineers and workers of Ansaldo and Klonne, who between 1935 and 1937 drove 1,500 piles into the mud of the Tiber and assembled 3,000 tons of iron, are the real authors. We don't know their names. The sources consulted do not report the name of the designer of the large gasometer, and the fact is not published in the institutional entries. It is a work of engineering without a signature, like many of the period.

Rita Levi Montalcini, Nobel Prize in medicine, who died in 2012, did not pass through the gasometer, but the bridge from which it is best seen carries her name, dedicated to her on July 8, 2014. Mimmo Paladino signed the poster of the 2025 exhibition Arte al Gazometro, curated by Marco Capasso with 19 artists. Giulio Vesprini painted the Ponte della Scienza in 2024.

And then the students. Roma Tre University, founded in 1992, has brought thousands of young people to the area, with campuses made out of reclaimed industrial buildings: the former Vetrerie at Via Ostiense 161 for Law, the former Alfa Romeo at number 234, the former Vasca Navale on Via Vito Volterra for Engineering, the Ex Mattatoio for Architecture. The gasometer is the daily backdrop of a whole generation of university students.

Eni, Roma Tre and the projects announced for the area

The owner is Eni, and on its website the company describes the area as transformed from industrial archaeology into an innovation district. Today you find ROAD here, the district born on May 17, 2023 that for the period 2026-2029 says it is working on infrastructure resilience, urban energy management with digital twins and advanced mobility, with an autonomous-driving test track called FULL ROAD.

In the same complex are the Joule business school, the ZERO accelerator, built with CDP Venture Capital, the Eni 2050 Lab exhibition space, the Enilive Academy for training on the energy transition and the newsroom of the news agency AGI. Two sheds built between 1909 and 1920, according to Eni, were originally workshops. It is a corporate campus, and that is what explains the fences and the controlled entrances.

Roma Tre has a different role. It does not own the gasometer area, but it has been the engine of the district's transformation. According to the university's director general, interviewed by LifeGate in 2026, the regeneration of Ostiense began 30 years ago precisely with the arrival of the university in the disused industrial buildings. The university also appears among the partners cited by Eni for the Gazometro opening program.

The Rector's Office building deserves a chapter of its own, designed by Mario Cucinella on an area that housed the Ente Comunale di Consumo and inaugurated in 2021. In the same area, at the crossing of Via del Porto Fluviale and Via delle Conce, the former Air Force barracks, occupied for housing since 2003, has been transformed with PNRR funds into 54 public housing units of Roma Capitale, with the keys handed over in September 2026, as the entry on the Ex Porto Fluviale tells.

Then there are the projects announced but not yet realized. The Riva Ostiense park, 2,000 square meters between the Ponte di Ferro, the gasometer and the river, is listed as in design in March 2026. For the Mercati Generali the 2005 Koolhaas project was never completed. In 2017 some Roma Tre Architecture students had proposed an energy museum and a park toward the river, which remained an academic hypothesis.

Here comes the second contrarian opinion. Ostiense is told as a regenerated neighborhood, and in part it is. But the regeneration worked where universities and bodies with their own budgets arrived, and it stopped where public money or agreement among owners was needed. The Mercati Generali idle for over 20 years and the riverbank still without a park say the work is half done.

When it is closed and what not to expect

The interior is closed every day when there is no scheduled opening or event, that is, the vast majority of the year. There are no hours, no fixed day of the week, no telephone number to call for an individual visit. For the Gazometro Aperto openings the channel is the secretariat's email, for those of the FAI the Rome delegation, for Maker Faire the event's website.

Don't expect to climb. No documented visit includes access to the structure of the gasometer, neither to the service stairs nor to panoramic platforms. Whoever sees photos taken from above is looking at authorized drone footage or service images. And don't expect a museum: the guided route tells the history of the site, the cleanup and the activities of Eni, with panels and installations, not with collections.

Don't expect tourist-type services either. There is no bookshop, no café open to the public on ordinary days, and the restrooms are those of the event area during openings. On accessibility for those who move in a wheelchair, the pages consulted do not publish detailed information: it is best to write to the secretariat before booking and ask which parts of the route are level.

From outside, instead, the gasometer is always there. It doesn't close, it has no shifts, it depends on no one. It is one of the few twentieth-century Roman buildings you can enjoy for free at any hour, and perhaps that is why it is so loved. If you find the visit dates sold out, you lose almost nothing. You always have the bridge and the lungotevere, which are the best part.

Eating in the area

Ostiense is one of the areas of Rome where you eat best and where it is easiest to go wrong, because the places are many and change often. Along Via Ostiense and in the streets around the Mercati Generali you find everything, from the neighborhood trattoria to the evening spot. Without naming any, there are signals that help you understand where not to sit, and they hold here as in the historic center.

First signal: the photo menu. If outside the door there is a board with photos of the dishes, translated into four languages, that kitchen works for those who pass once and don't come back. A Roman doesn't need to see the photo of a carbonara to know what he is ordering. It is not snobbery, it is simple observation of who the customer is that the place is aimed at.

Second signal: the lady rolling out fresh pasta in the window or on the street. It makes a scene, it catches the eye, but good fresh pasta is made in the kitchen early in the morning. When it becomes a show in front of the entrance, it is working as a lure for passersby. Third signal: the barker, the person at the door who stops you to invite you in. A place with regular customers has no need to go and fetch them in the street.

Fourth signal: the kitchen always open, from morning to night, with no break. A real kitchen crew stops in the afternoon to prepare for the evening. Fifth signal: items without a price, the fish of the day with no figure next to it, the menu different between the tables outside and those inside. Always ask the price before ordering, especially when the waiter suggests a dish aloud.

On the days of Maker Faire and the events at the Gazometro the area fills up and the prices of those who work on passing trade tend to rise. It is the moment when the improvised places, with little tables on the sidewalk and a handwritten price list, do the most business. If you can, eat before or after, moving a few streets toward Garbatella or toward the Testaccio market.

The Nuovo Mercato Testaccio is a good solution for a quick lunch, with stalls serving ready food next to those of fruit and vegetables. For the city's neighborhood markets you find an overview on the page about the markets of Rome. Check the hours, because in the afternoon and on Sunday many stalls are closed.

The criterion stays the same: look at who is sitting. If at lunchtime there are employees from the nearby offices, Roma Tre students and families from the neighborhood, you are in the right place. To orient yourself without going at random, I keep up to date our list of the places where we eat, in Rome and around, with no sponsorships.

What to pair it with in a day

The natural pairing is the Centrale Montemartini, the power plant inaugurated in 1912 turned into a museum with ancient statues among turbines and diesel engines. It is on Via Ostiense, a few minutes from the gasometer, and is the key to understanding the district: the same industrial season, the same relationship between machine and city. Morning at the Centrale, sunset on the Ponte della Scienza.

Then the street art. According to LifeGate, in the area you find Il Nuotatore by Agostino Iacurci, from 2011, Hunting Pollution by Iena Cruz, from 2018, the large ecological mural painted with smog-absorbing paint, the Wall of Fame by JB Rock and a mural by Giulio Vesprini that dialogues with the gasometer. The full route is on the page about street art in Ostiense and on the one about street art in Rome.

Toward the north the walk leads to Testaccio. The Monte dei Cocci, the hill made of broken amphorae, the Non-Catholic Cemetery next to the Pyramid, the Ex Mattatoio and the Museo diffuso del rione fill half a day. From Porta San Paolo you climb toward the Aventine and the Orange Garden.

Toward the south Via Ostiense leads to the Basilica of St. Paul Outside the Walls, one of the four papal basilicas. Inside Porta San Paolo is the Via Ostiense Museum, small and little visited, housed inside the gate itself. Continuing along the same axis you reach EUR and, farther on, Ostia Antica.

For those following the thread of the twentieth century and industrial architecture, the other stops are the Archivio Storico e Museo Birra Peroni, the MAXXI for the contemporary and the Forte Bravetta for the memory of the century. Those who prefer the river find ideas on the page about Rome at night, and beyond the Tiber, within bicycle reach, there is Trastevere with Porta Portese.

Frequently asked questions

Can you go inside the Gasometro of Rome?

Not freely. The area is private, owned by Eni, and you enter only during the Gazometro Aperto guided visits, organized with the FAI by reservation, during the FAI visits for members and on the occasion of events such as Maker Faire Rome and Videocittà. In no case do you go up the structure. From outside the gasometer can be seen for free at any hour from the bridges and the lungotevere.

How much does the guided visit cost?

In the 2024 and 2025 editions of Gazometro Aperto the visits were free with mandatory reservation, according to the sources consulted. For the 2026 edition the official calendar lists the dates but does not give the cost, and as of the verification date all registrations show as closed. For information on new dates the only published channel is segreteria@enigazometroaperto.it. Maker Faire Rome instead has its own ticket.

How tall is the Gasometro?

The large gasometer is 89.10 meters tall according to Wikipedia, almost 90 according to the City of Rome. The diameter is 63 meters for both sources, while a 2025 article gives 60. It was built between 1935 and 1937 by Ansaldo of Genoa and Klonne of Dortmund, with about 3,000 tons of iron, and could hold 200,000 cubic meters of gas.

Is it Gasometro or Gazometro?

The Italian language accepts both forms, but in Rome it is said Gazometro, with the z, and that is how the City, Eni, the FAI and most sources write it. The visit program is in fact called Gazometro Aperto. If you search for it online, or if you ask a passerby for directions, use this spelling and you'll get there faster.

Where can you see the Gasometro best from?

The best spot is the Ponte della Scienza, pedestrian and bicycle, which starts from Riva Ostiense right level with the gasometer and leads to the Lungotevere Vittorio Gassman. Good views also from the lungotevere on the Marconi bank, from the Ponte dell'Industria reopened in 2025 with a pedestrian walkway, and from Via del Porto Fluviale. The ideal moment is sunset, with the gasometer against the light on the sky.

How do you get to the Gasometro by public transport?

The most convenient solution is metro B to Piramide, then about a kilometer on foot, 10 or 15 minutes. Alternatively the Roma Ostiense station, also a kilometer away, where the FL1 train from Fiumicino arrives. ATAC lines 23 and 769 stop on Via Ostiense at the Ostiense/Mercati Generali stop, near Via del Commercio 9-11 entrance.

Who owns the Gasometro?

According to Wikipedia and the Eni website, the Gazometro complex belongs to Eni, which has owned it since 1967 after the passage through Snam and Italgas. Originally the plant belonged to the Società Anglo-Romana per l'illuminazione di Roma col gas. Today the area hosts the ROAD innovation district, the Joule business school, the ZERO accelerator, Eni 2050 Lab and the newsroom of the AGI agency.

In which films does the Gasometro appear?

The City of Rome lists among the works that used it as a backdrop Accattone by Pier Paolo Pasolini, from 1961, Troppo forte by Carlo Verdone, from 1986, Le fate ignoranti by Ferzan Özpetek, from 2001, and Romanzo criminale by Michele Placido, from 2005. In 2023 the Måneskin shot the video for the song Honey there. It is one of the most recognizable urban sets in the city.

Who wrote the page

The page comes from the team at Tour Leader Pro, the Rome-based outfit that designs itineraries, visits and cultural events across Rome and Lazio. Opening dates, access arrangements and connections given here come from the official sources cited in the text as of the date stated at the top. Since it is a private area with only scheduled openings, recheck them before heading out and tell us what you find changed.

Building a day in Ostiense means fitting together guided openings that sell out in a few hours, events that fill the district, museums with different hours, bridges and quays that stay closed after floods, for yourself or for a group of 40 people. Whoever faces this kind of puzzle will find on Tour Leader Pro working materials designed for those who lead and for those who organize on their own.

For the wide picture, that is regional trains and seasonal schedules, connections with the airports, moves from one province to another and Lazio destinations outside the center of Rome, from the coast of Ostia to the Castelli to the volcanic lakes of the north and the villages of the interior, a useful resource for putting together a multi-day itinerary is Italy Planner.
