The construction of the fort at the top of Mont Chaberton began in 1892. The idea was then for the Italian army to strengthen its defense system against France. Nicknamed then the "Fort of the Clouds", it was at that time the highest fort in the world. Its position is extremely strategic, and almost unbeatable: it is located on a ridge line, at more than 3,130 meters above sea level. The fort became French in 1947, along with Mont Chaberton. Today, only ruins remain, which are truly impressive!
Mount Chaberton culminates at 3,131 meters above sea level. It offers a beautiful panorama over the valley of the Petite Durance. You will find several orientation tables there to identify the surrounding peaks. Like Mont Thabor, Chaberton became French in 1947. By moving the border to the entrance to the village of Clavière, the Treaty of Paris allowed France to annex the summit.
