Fort des Têtes

The Fort des Têtes, also known as the Fort des Trois Têtes, is a fortification in the vicinity of Briançon in the Dauphiné region of southeastern France. Partially designed by Vauban, the fort was first established as a permanent fortification in the 1720s and was used by the French army until 1940. Owing to its testimony to the advancement of military fortifications and Vauban's influence in military architecture, it was listed as a UNESCO World Heritage Site in 2008.
