Fort des Rousses

Fort des Rousses is a large military fortress at 1150 meters elevation featuring extensive vaulted chambers and underground passages throughout its structure. The subterranean design maintains consistent temperature and humidity levels year-round.

Construction began in 1800 under Napoleon's orders to protect Alpine territory and took decades to complete. The fortress became one of France's largest military installations of its era.

The fort now functions as a storage facility for Comté cheese, shaping daily life in this mountain region. You can walk through the vast chambers where thousands of cheese wheels rest in the cool underground environment.

The fort is reached by a scenic mountain road with switchbacks, and interior paths are clearly marked. Bring warm clothing as underground areas stay cool throughout the year.

In 1997 this military installation was transformed into a cheese storage facility, taking advantage of the existing underground structure's natural properties. This conversion demonstrates how historic buildings can serve entirely new purposes.
