Aventicum Archaeological Site

Aventicum is the Roman-era city located at modern Avenches in the canton of Vaud, which served as the capital of the Helvetii during Roman rule from the 1st century AD.

The site contains major archaeological remains including an amphitheatre, stretches of city walls and the Roman street layout; these are the main reasons visitors come. Excavated artifacts are displayed in the local museum, which interprets the urban plan and public buildings of the ancient city.

Aventicum was developed under Roman administration as a provincial capital and urban centre, with public buildings, temples and defensive works. Over the centuries the site was abandoned and buried, with systematic archaeological excavations beginning in the 19th and 20th centuries that recovered much of the visible remains today.

The ruins sit at the location of modern Avenches in Vaud, roughly midway between Lausanne and Bern in western Switzerland, on agricultural lowlands above the Broye plain.

• Site accessibility: Many ruins are concentrated around modern Avenches and are accessible on foot; the local museum provides context for the excavated remains.

What to See#

• Amphitheatre: A large Roman-era amphitheatre located on the outskirts of modern Avenches, where excavations have revealed seating and entrance structures from the Roman city.
• City walls and street plan: Sections of the city walls and street grid remain visible across the site, marking the layout of the Roman municipal centre.
• Avenches Roman Museum: A local archaeological museum displaying finds from the site, including inscriptions, sculptures and everyday Roman objects recovered during excavations.

Aventicum refers to the Roman archaeological site in the town of Avenches (canton Vaud). By car from Lausanne, follow the A1 motorway toward Bern and take the exit for Avenches; the drive is typically around 30-45 minutes depending on traffic (roughly 35-45 km by the motorway route).

Avenches is also served by regional public transport: Payerne is the nearest larger rail hub and local buses or a short taxi ride link Payerne station to Avenches. The ruins and museum are within easy walking distance of the town centre.

• Arrive by train to Avenches station and walk to the archaeological park and Musée romain d'Avenches to avoid constrained parking near the site.
• Avoid days when the amphitheatre hosts summer events if you want a quiet exploration of the ruins, or conversely check the event calendar if you prefer to see the amphitheatre in use.
• Buy a combined ticket for the Roman museum and the open-air site so you don't miss the indoor mosaics and artifacts that many visitors skip when only touring the ruins.
