Used as a site of camp as early as 1890, the camp was built between 1896 and 1910 and improved until the second world war.
The set consists of twenty-six small buildings, including 20 almost identical with the appearance of cottages but, given the difference of the materials used, would certainly not been built at the same time. Some time later they added a cable car and a command post with a mess for officers and an optical telegraph office upstairs.
These cottages were used primarily for housing and could accommodate a battalion of four Alpine companies of 150 men who were living in austere conditions. The camp was equipped with kitchens, storerooms, toilets and a bread oven. The cable car, built in the thirties, which connected the village of Pra, would allow for re-supplying or evacuation of casualties (The cable car was destroyed in 2005 to allow for the widening of the road at the entrance the village). Stables were used to house the mules.
The camp was permanently occupied, but during the winter there was a reduced charge just to guard the road, traffic between the chalets was managed by tunnels under the snow on wooden boardwalks.
An esplanade south of the position also allowed to erect tents in summer.
Although located close to the outpost of the Col du Fourches which was attacked in June 1940 and September 1944, it does not appear that the camp itself was affected by the fighting.
