Just before the Second World War, the French army decided to build fortifications (bunkers) on Col de Gialorgues with a few to stopping a possible Italian invasion. Military authorities aimed to open a sufficiently wide track to allow all-terrain vehicles to reach Col de Gialorgues. Materials were transported by mules from the camp which was set up at the foot of the Estenc woods, but the soldiers had to rapidly give up due to the stony nature of the ground.
