Fortifications in Briançon

Briançon’s defensive network, a UNESCO World Heritage site, represents the pinnacle of mountain fortification designed by military engineer Vauban. Constructed between the 17th and 19th centuries, this high-altitude complex protected the strategic Alpine border with Italy. The system includes the massive Fort des Têtes, the unique Communication Y gallery, and several satellite forts like Salettes and Randouillet, all positioned to control the Durance, Guisane, and Clarée valleys.
