Typical for this region are the enceintes or camps: massive fortified enclosures, perhaps for protection of the inhabitants of the neighbourhood, constructed in the early Iron Age from enormous stones. The walls are often up to 4 m. high, and some enclosures have several concentric ramparts.
Camp de Soubeyran faces south on a hill SW of St. Cezaire-s-Siagne, and was perfectly sited for surveillance of the valley.
