Fort de Cindey, Military fortress in Saint-Maurice, Switzerland

Fort de Cindey (army designation A 155) is a former artillery work cut into the Scex escarpment above the Château Saint-Maurice, on the left bank of the Rhône. Its main gallery runs parallel to the rock face about 25 metres inside the cliff, with side galleries reaching the face for observation posts and gun casemates, and branches leading to troop quarters, the command post and ammunition magazines. The entrance lies in the Grotte aux Fées, a natural cave that the army widened into a walkable tunnel linking the fort with Fort du Scex a kilometre to the south.

The fort was built in two construction phases and completed in 1954 as part of Switzerland's defensive strategy during the Cold War. It formed one section of a larger national defense plan focused on protecting the Alpine border regions.

The fort displays equipment and spaces that show how Switzerland prepared its defenses during the Cold War era. Visitors can see the actual chambers where soldiers trained and stood watch over the valley.

The fort opens during summer months and visitors reach it through guided tours arranged by the Saint-Maurice Tourism Office. Wear sturdy footwear since the underground paths and corridors have uneven surfaces and steps.

The entrance to Fort de Cindey lies inside the Grotte aux Fées, a natural cave that the army widened into a walkable tunnel and that also links the fort with Fort du Scex one kilometre to the south. In peacetime the garrison drew its water from Saint-Maurice; for war, an underground intake was built in the cave directly at the waterfall.
