Historic site: Two earth and rubble ramparts habe been attributed to the neolithic/chalcolithic periods and a third to the Bronze Age. Before the Bronze Age, a copper axe found proves that this site was also inhabited during the Copper Age period. Iron Age occupation is attributed by six pieces of iron found at this place. In Roman times, a Gallo-Roman temple was built here. Extensive, careful excavations have brought hundreds of artifacts from the five different peoples to light.
