Briançon Old Town (Cité Vauban)

A UNESCO World Heritage site, the fortified old town of Briançon is a labyrinth of narrow streets, historic buildings, and impressive ramparts designed by Vauban in the 17th century. Visitors can explore the Collegiate Church, the Maison du Roy, and walk along the city walls offering panoramic views. It's a cultural and historical gem, free to explore, with guided tours often available in peak seasons. Several small museums and artisanal shops are also present.
