This is ancient land bearing traces of the Neolithic Age, 5 000 years B.C.
Roquefort lies on a promontory (a Gallic oppidum area with a triangular form) delimited by several streams, the Engranne in the north-east, the Petite Engranne or the Roquefort stream in the south-east (see vine map). The very steep slopes on each side of this promontory discouraged attackers. A covered alley, i.e. a burial place, dates from this period. (14 metres long by 1.40 wide comprising 22 blocks and 3 tables are still present).
