Communication Y, Military monument in Briançon, France.
Communication Y extends as a vaulted gallery measuring 200 meters in length and 4.5 meters in width, connecting Fort des Têtes to Fort du Randouillet.
The construction of this military passage occurred between 1724 and 1734, following designs by engineer Tardif in 1711 and subsequent plans by engineer Nègre in 1721.
The structure represents French military engineering excellence, forming part of the defensive network that earned UNESCO World Heritage status in 2008.
