The oppidum of Ensérune, occupied from the Early Iron Age right through to the Gallo-Roman period, is one of the largest ancient hill towns in France's Mediterranean region. The digs carried out starting in 1915 have unearthed the remains of various settlements from the 6th century BC to the 1st century AD. Most of the finds are on display at the museum. Alongside the tour of the site, the emphasis is placed on more practical aspects such as learning about pottery techniques and everyday life.
