 During the early Middle Ages, the castle promontory was occupied by a cemetery, of which several ditches cut in the rock have been found.Of the first enclosure there remains a large gatehouse or "châtelet" (12th, 14th and 15th centuries), with machicolations and embrasures for cannons (about 1400).This gateway gave access to the first level of the promontory, dedicated to the activities of the garrison and the servants.
