The Monte Viso Tunnel (Italian: Buco di Viso; French: Pertuis du Viso) is an Alpine pedestrian tunnel excavated in the rock during the Renaissance and located eight kilometres north of Monviso (Cottian Alps), northern Italy. It is 75 m long, 3 m wide, and located at an altitude of 2,882 metres linking the villages of Crissolo in the modern Italian province of Cuneo and Ristolas in the French department of Hautes-Alpes.
Opened in 1479, it is one of the most ancient tunnels of Italy and maybe one of the most ancient of Europe.
