"Crossing the dyke of the Plan d´Aval dam, you will notice its double vault construction standing on a rocky bastion. The dam is made of cut stone, part of which comes from the old quarry, known as the ""tile"" which now contains the car park. Built between 1945 and 1956, these two water reservoirs are integrated into the Haute-Maurienne hydrœlectric system and help to fill the Mont-Cenis dam."
