On 3 July 2026 the Roman theatre of Aosta reopened to the public after a closure that began in 2023. Entry was free from 3 to 5 July, and from 6 July the monument went back into the single «Aosta Archeologica» ticket.
Warning: the reopening is partial and the building site is still inside the monument. I am not saying this out of journalistic caution; the regional councillor Erik Lavevaz said it on the opening day: «What we are inaugurating is halfway between a proper visit and an open-air building site». When the people who commissioned the work describe it that way, their description is the most reliable figure available.
It is still worth going, and in this article I will try to explain why, what you will actually see, and what you will have to imagine until 2027.
What you see today, and what you do not
You enter from via Charrey, cross the piazza ex Birreria and walk along a raised walkway laid between the stage and the orchestra: you are standing, in other words, at the point where the action happened, with the cavea rising in front of you. That is a viewpoint the old route did not offer.
What you will not find is the monumental entrance from the Porta Praetoria, which was the historic way in, and the new ticket office, which is still to be built. Work on the «Aosta est» area continues from 1 July 2026 to 30 June 2027 and includes the ticket office, an electrical substation, a public terrace and the repaving of rue de Baillage. The wider project also covers the Porta Praetoria, the Torre dei Signori di Quart, the Roman walls and the Tour Fromage.
Warning: some outlets ran the headline «reopens after seven years». The local papers closest to the facts date the closure to 2023, so about three years. If you read «seven», you are reading a count that no primary source confirms.
Twenty-two metres of façade, and how to read them
Why is the theatre of Aosta recognisable in a photograph even to people who have never been there? Because what survives is not the cavea, as at Trieste, but a wall. The southern façade is twenty-two metres high, ribbed by buttresses and lightened by three tiers of windows that shrink as they climb: great arches at the bottom, a row of narrow openings in the middle, four arched windows at the top.
That wall is not the theatre’s stage building. It is the outer wall that closed the complex on the city side, and its height is the reason the monument reached us at all: it was too big to dismantle comfortably and too useful to knock down. Over the centuries houses leaned against it, and the lower part stayed embedded in the urban fabric.
The detail I suggest looking for is the stone. Compare the squared blocks of the buttresses with the infill between one and the next: two materials and two ways of working, and the difference tells you how the Romans saved good stone by putting it only where it had to carry weight.
A theatre for four thousand in a frontier colony
Estimates give the theatre between three and four thousand spectators, with an orchestra ten metres in radius, and the construction goes back to the 1st century BC, with later ancient alterations.
The number deserves a moment of attention, because it is out of proportion and the disproportion is the point. Augusta Praetoria was founded in 25 BC immediately after the victory over the Salassi, the people who held the Alpine passes, and it was founded as a garrison on the road to the Little and the Great St Bernard. A frontier colony did not need four thousand seats to entertain its settlers: it needed to demonstrate, to anyone arriving from the passes, that behind those walls stood Rome in full, with its spectacles and its architecture. The theatre is a political statement built in stone.
What «open to visitors» means, and why the answer here is honest
It is worth pausing on this, because it is rare. In Aosta the monument reopens halfway and says so: the official communications talk about a partial route, give the dates of the remaining work and quote the councillor on the open-air building site.
The comparison I have in mind sits at the other end of Italy. In Cagliari the Roman amphitheatre has been closed to visitors since 2011, and the city council’s own page, the owner’s own page, went on publishing opening times and prices as though it were open: I wrote about it in the guide to Cagliari in two days. Fifteen years of closure kept quiet on one side, three years of closure and a reopening announced for exactly what it is on the other. As a reader I much prefer the second, even if it makes me walk on a temporary walkway.
The walls of Augusta Praetoria, which are the city’s real monument
The theatre leans against the walls, and the walls are the largest thing Aosta owns. The circuit measured about 2.6 kilometres and drew a rectangle of 727.5 by 574 metres, its sides matching the maximus decumanus and cardo: the plan of today’s city is still that one.
The structural figures run as follows. Thickness at the base about 1.9 metres, height about 6.5 metres, a core of opus caementicium made of river pebbles faced on the outside with small travertine blocks, and a crenellated walkway on top. And twenty towers: four at the corners, eight on the stretches between corners and gates, and eight in pairs flanking the four gates, which were the Porta Praetoria to the east, the Decumana to the west, the Principalis Sinistra to the north and the Principalis Dextera to the south.
Eight towers still standing, and the reason is not a love of antiquity
How many cities can say they still have eight towers from their Roman circuit? Aosta can, and the reason is less noble than it sounds: those towers were not preserved, they were used. Nobody ever took their roofs off, and a building with a roof does not collapse.
The use is still legible in the names and the addresses. The Torre dei Balivi, the north-east corner tower, houses the conservatory today. The Torre del Lebbroso is a regional exhibition venue. The Tour Perthuis is embedded in a school building. The Tourneuve, cylindrical, stands in via Monte Solarolo. The castle of Bramafam joins a cylindrical tower to a residential block. The Torre Plouves was restored in 2010. And the Tour du Pailleron, the one in the photograph above, is reckoned the best preserved: six openings a side, a lower part in Roman stone and an upper part rebuilt in brick, facing the station forecourt.
This is the lesson you carry away from Aosta and will not find in a museum: a monument survives when it stays convenient. The same mechanism saved an entire Roman town in Molise, Saepinum, where the village houses rest on the ancient walls and for that reason hold them up. The Tour Fromage, of the 11th and 12th centuries, is now an exhibition space, and its restoration belongs to the same building site that kept the theatre closed.
Where to see the walls, street by street
There is no single signposted route, so here are the addresses. Stretches of Roman wall surface in via Hôtel des Monnaies, via Giosuè Carducci, via Giorgio Carrel near the bus station, via Monte Solarolo, via Abbé Chanoux, via Festaz, where the wall was breached to let modern traffic through, and via Amilcare Cretier.
Two stretches lie underground and can be seen only from inside: in the basements of Palazzo Roncas, home of the Regional Archaeological Museum, and in those of the Regional Library. The best way to understand the circuit, though, is still to walk round it: a little over two and a half kilometres, a good hour with stops, and at the end you will hold the shape of the Roman city in your head better than any plan could put it there.
Practical information
Details checked on 7 September 2026 on the official pages of the Aosta Valley Region and in local reporting on the reopening. Prices and opening times change: check again before you travel.
Tickets. The theatre sits inside the single «Aosta Archeologica» ticket at 10 euros, valid for six months, which also covers the forum cryptoporticus, the early Christian church of San Lorenzo, the Regional Archaeological Museum and the megalithic area. The reduced rate is 8 euros and applies to groups of twenty-five and to guided tours. The 19-25 band pays 3 euros. Buying online is recommended.
Opening times. From April to September the site opens 9:00-19:00, from October to March 10:00-13:00 and 14:00-18:00. Closed on 25 December and 1 January. Last entry is thirty minutes before closing.
Free admission. Under 18s go in free, as do people with certified disabilities and one companion, school groups with their teachers and holders of the museum pass.
Warning: one divergence the sources do not settle. The regional institutional pages, last updated in 2023, state that admission is free from 0 to 25; the regional tourist portal instead gives free under 18 and 3 euros for the 19-25 band. If you are between 19 and 25, telephone the Archaeological Museum on 0165 275902 before counting on free entry.
Getting there. The theatre stands in via Porta Praetoria, in the heart of the old centre, ten minutes on foot from the railway station. Until the work finishes, access is from via Charrey. The site has no architectural barriers.
How long it takes. Half an hour for the theatre area, a good hour if you add the walls and the Porta Praetoria, which stands fifty metres away and costs nothing.
The rest of Aosta
The theatre is a half-hour stop inside a day that has to be fitted together monument by monument: the full itinerary, with the calendar that decides what you get to see, is in what to see in Aosta in one day. The other four pieces are the collegiate church of Sant’Orso with the cloister and the forty capitals, the cathedral with the choir mosaics and the treasure museum, the megalithic area of Saint-Martin-de-Corléans and the arch of Augustus with the stone bridge.
