The Fort de l'Olive was armed in the 1880s with fourteen 120mm guns. It was initially linked to the Fort de l'Infernet by optical telegraph, and later by telephone. A cableway provided a means of resupply from the valley below, particularly in the winter when road access was difficult. The Batterie du Lenlon was a subsidiary position, as was the Batterie du Sapey. The site is abandoned but in good condition, and is freely accessible. ==References==
