Mont Cenis (Italian: Moncenisio) is a massif (el. 3,612 m / 11,850 ft) and pass (el. 2081 m / 6827 ft) in Savoie (France), which forms the limit between the Cottian and Graian Alps. The pass connects Val-Cenis in France in the northwest with Susa in Italy in the southeast. In the Middle Ages, pilgrims passing through Moncenisio and Susa Valley came to Turin along a road called Via Francigena, with final destination Rome. It was one of the most used Alpine pass in from the Middle Ages to the nineteenth century. The pass was part of the border between the two countries from the annexion of Savoy to the third French Empire in 1861 until 1947 Treaty of Paris, but is now located completely in France. The treaty allowed Savoy to retrieve its historical and political boundaries.
