Fort de Montgilbert

Fort de Montgilbert is a triangular fortification positioned at 1360 meters elevation in the Savoie department with multiple defensive structures arranged around a central courtyard. The complex includes barracks, ammunition storage facilities, and gun positions built into stone and earth.

The fort was constructed between 1877 and 1882 as part of the Chamousset fortress system designed to control the Arc Valley. It was positioned as a strategic defensive line along important regional routes.

During World War II, the fort area became a resistance point, marked by a weapons airdrop operation on December 15, 1943.

Access is via hiking trails from the Les Bugnons hamlet following yellow markings through a forest path with approximately 450 meters of elevation gain. The hike is manageable on foot but requires proper gear and some stamina due to the climb.

The fort retains original features like a bread oven and period woodwork that show what life was like for the garrison. The powder magazine is particularly interesting for its specialized ventilation systems that prevented dangerous gas accumulation.
