From the cross looking south-east, you can see the Chevril hydrœlectric dam, established on the Isère river below the ski resort of Tignes, which is the only access road. At the time of its construction in 1952, it was the highest arch dam in Europe at 181 metres high. Its impounding caused the engulfment of the old village of Tignes, populated back then by 387 inhabitants. The expropriated families were relocated to the new village of Boisses (village located at the foot of the dam).
