Entremont (oppidum)
Entremont is  a 3.5-hectare (8.6-acre) archaeological site three kilometres from Aix-en-Provence at the extreme south of the Puyricard plateau. In antiquity, the oppidum at Entremont was the capital of the Celtic-Ligurian confederation of Salyes. It was settled between 180 and 170 B.C., somewhat later than the inhabitation of other oppida, such as Saint-Blaise (7th to 2nd centuries B.C.). The site was abandoned when it was taken by the Romans in 123 B.C. and replaced by Aquae Sextiae (modern Aix-en-Provence), a new Roman city founded at the foot of the plateau.
