The Arc is an 83km (52miles) long river in Southern France. It arises at an elevation of 470m (1,540feet), close to the village of Pourcieux. It then passes through Aix-en-Provence before flowing into the Étang de Berre, a lagoon connected with the Mediterranean Sea to the west of Marseille. Its drainage basin, with a surface area of 716km2, is divided between two départments, Var and Bouches-du-Rhône.[1] The Bayeux, the Cause and the Torse are its tributaries.
The Roquefavour Aqueduct passes over the river; Paul Cézanne's Mont Sainte-Victoire and the Viaduct of the Arc River Valley is the best known piece of art representing the Arc.
