The archaeological site beneath the parish church of Saint-Vincent is testimony to a continuous occupation starting from the first settlements dating back to the Late Bronze Age / Iron Age. In Roman times (2nd- 4th centuries AD), various buildings with a thermal function were discovered.
After the beginning of the 5th century AD, the area was occupied by tombs, typical of early Christianity, that were positioned from east to west.
Their presence seems to have led to the foundation of a first funerary building. Further stages of burial followed in the 7th and 8th centuries, prior to the erection of the Romanesque church.

Visitors can discover the site using a didactic route fitted with information panels and multimedia support.
