Augusta Raurica

A city spread between Augst and Kaiseraugst

East of Basel, Augusta Raurica occupies more than a single enclosure of ruins. Across Augst and Kaiseraugst, streets, public buildings, workshops and the later Rhine fortress preserve different parts of a Roman urban world. The pleasure of the site lies in moving between them. A theatre gives the city an immediately recognisable scale, but a house, a drain or an object recovered from rubbish can reveal just as much about the people who lived here.

The official history distinguishes the colony’s founding act from the actual construction of the town. Building began after a refoundation under Augustus, from around 15 BCE, following delays associated with the civil wars after Caesar’s death. That distinction prevents a ceremonial foundation from becoming the date of every excavated street. On the plateau at Augst the town developed, while towards the Rhine at Kaiseraugst there was a military camp; early construction relied substantially on timber.

The later city acquired stone buildings and a developed public landscape. Its remains invite a connected reading rather than a hunt for isolated attractions: the forum concerned civic authority, performance buildings gathered audiences, baths and workshops belonged to ordinary routines. The settlement changed over time instead of remaining fixed at a single imperial moment. Its later shift towards the fortified riverside makes that evolution particularly clear.

Theatre, house and a different kind of evidence

The theatre in the former centre is the third structure erected at that position. The official account estimates an ancient capacity of about ten thousand spectators and distinguishes it from the separate amphitheatre on the southwestern edge, in use from around 200 CE. Plays, religious festivities and political gatherings belonged to the theatre’s history. Its present appearance also reflects excavation and substantial conservation: the monument is ancient, but its legibility owes much to later work.

The Roman House offers another way into everyday life. It is a modern reconstruction modelled on a Pompeian town villa, not an intact local dwelling discovered complete with its furniture. A courtyard, kitchen, private bathing space and street-facing workshops turn domestic organisation into something more tangible. The reconstruction is valuable precisely when its status is understood: it interprets ancient living arrangements without making every visible wall an original survival from Augusta Raurica.

Even this carefully presented house has changing conservation conditions. The operator currently notes that the large dining room is cordoned off in connection with the Hölstein mosaic. A visit should not therefore promise unrestricted access to every furnished space. The same principle applies to the wider archaeological park. Preservation is part of the experience, and the work that keeps a monument understandable can sometimes make a room temporarily unavailable.

The treasure that is not currently on display

The late Roman silver hoard from Kaiseraugst remains one of the site’s defining discoveries: approximately fifty-eight kilograms in some 270 objects, including tableware, spoons and coins. It was buried around 351 CE in the Castrum Rauracense, the fortress established beside the Rhine around 300. The deposit connects fine craftsmanship with uncertainty and power in the later empire. Its burial and eventual recovery belong to a different phase from the earlier colony’s growth.

Today’s practical distinction is essential: Augusta Raurica’s official museum and treasure pages state that the silver hoard is not currently exhibited in the museum. Selected objects can be studied through the digital cultural-property catalogue. The collection’s importance has not diminished, but it should not be advertised as a guaranteed highlight waiting in a display case. Anyone travelling chiefly to see the original silver should confirm a future exhibition announcement before choosing a date.

The museum’s changing exhibitions draw on a much wider archaeological collection. Its presentation of an ancient banquet, for example, uses discarded food and objects to ask how status was expressed through eating and consumption. This is a useful counterpoint to monumental ruins: the remains of an event can be found in what people threw away. Archaeology reconstructs social choices through ordinary material, as well as through a spectacular treasure buried in a time of crisis.

Current closures, seasonal hours and the next festival

Check dated notices before relying on general hours. As verified on 29 October 2026, the museum’s exhibition rooms were closed for a changeover from 26 to 31 October; the Roman House remained accessible free of charge during that interval. The published regular November–February timetable is Tuesday–Sunday, 10:00–15:00, with specified holiday closures. The outdoor grounds are listed as freely accessible year-round. These are different arrangements, and an open archaeological landscape does not imply open exhibition rooms.

The Römerfest also requires a specific year. The planned 29–30 August 2026 edition was cancelled because of prolonged heat and drought; it should not be described as an event that took place automatically on the last weekend of August. The operator announces the next edition for 28–29 August 2027. Those are planned future dates, to be checked again before booking around them, rather than a timeless annual promise.

For public transport, the official approach uses the S1 from Basel SBB to Kaiseraugst station, followed by a walk; the operator explicitly distinguishes it from Salina Raurica. Consult the current timetable and site map, especially when combining widely separated monuments. Leave time for the less spectacular evidence between them. Augusta Raurica becomes a more convincing Roman city when theatre, domestic interpretation, buried objects and the continuing care of the site are read together, with current access conditions allowed to shape the visit.
