What is "roquepertuse"

Acropolis Roquepertuse is a historical religious center for the Celts. It is located near the city of Velaux, north of Marseille and west of Aix-en-Provence, in the Provence-Alpes-Côte d'Azur région of southern France. Roquepertuse had no domiciles available for worshippers and has been used as a sanctuary where only priests may have lived permanently. It was destroyed by the Romans in 124 BC and was discovered in 1860. Most of the excavations were done in 1923 by H. de Gérin-Ricard.
