Redoute Marie-Thérèse

Redoute Marie-Thérèse is a fort in the Alps featuring a horseshoe-shaped layout with a central courtyard and a drawbridge controlling access. The structure displays strategically positioned defensive walls and gun emplacements built into the mountainside.

Built between 1817 and 1834 by the Kingdom of Sardinia, the fort was constructed to monitor the Mont-Cenis mountain pass and road. It served as part of a defensive line of five fortifications protecting against potential French military movements.

The name honors Maria Theresa and her role in Alpine regional affairs. Visitors can explore exhibitions about military life and mountain communities, showing how people adapted to this challenging terrain.

The fort is open to visitors mainly during the summer months and offers guided tours and interactive activities. Wear appropriate footwear and allow time to explore the exterior areas, as the approach involves climbing uphill on a mountain slope.

The fort was designed so that its garrison could live completely independently, with internal workshops, storage areas, and water systems built into the structure. This self-sufficiency was essential for withstanding long sieges without needing outside assistance.
