The modern town of Avenches lies on part of the former capital. Across the whole are the several Roman structures - two roman temples, an amphitheatre, an open air theatre, several sections of the wall surrounding the town, bath house and the eastern gate.
The baths also known as "Thermen von En Perruet" or "Baths of Forum" were baths located direcly east of the forum in Aventiucm. They were built during the expansion to a colony around 77 AD. Foundations are all that remains of the baths. The remains are located under a building which allows visitors to view the foundations up close.
