The Chablais and Chillon forts were not considered part of Fortress Saint-Maurice proper, but were important advance works to delay and weaken an attacker before they reached the Saint-Maurice stopping line, or ''fort d'arrêt''. The entire region is fortified with anti-tank barriers, permanent minefields and other barriers, while tunnels, bridges and retaining walls are mined or prepared for demolition. Construction at Champillon began in 1942, and was complete in 1944. The fort is located in a massif overlooking the Rhône beneath

s, cut into the rock face of the west-facing cliff. An underground passage runs back into the mountain to ammunition magazines, utility areas and two-story underground barracks. The fort's entrance is on the plateau behind the fort. Two additional 105mm casemates, each with their own magazine, were planned but never built. A variety of smaller blockhouses, observation posts, anti-tank lines and infantry shelters are in the immediate area, none connected directly to Champillon. The position was manned by elements of Fortress Regiment 19, and was designated part of Fortress Group 4.

Present situation

The Fort de Champillon was decommissioned in 1994 and sold to private owners in 2005. In 2010 plans were announced to install the Swiss Explosives Museum in the site, called ''Pyromin''. A portion of the fort is used by NL Pyrotechnics as a warehouse. The fort and museum are planned to be opened to the public.
