The Fort de Chillon is a twentieth-century fortification directly adjacent to the medieval Château de Chillon on the edge of Lake Geneva in Switzerland. The fort secures the road and rail lines that pass along the lakeshore running east from Lausanne to the mountainous interior of Switzerland. The position is an advanced work protecting the approaches to Fortress Saint-Maurice, part of the Swiss National Redoubt. Deactivated as a military post in 1995, it is privately owned and has been converted into a museum.
