Col de Tende (elevation 1870 m) is a high mountain pass in the Alps, on the border of France and Italy. It separates the Maritime Alps from the Ligurian Alps. It connects Nice and Tende in Alpes-Maritimes with Cuneo in Piedmont. A railway tunnel inaugurated in 1898 and a Road Tunnel inaugurated in 1882 run under the pass. The latter tunnel is 3.2 kilometre long and is among the oldest long road tunnels. French historian François Guizot states that the road was first developed by Phoenicians and later maintained by Greeks and Romans.
