Rove - Tunnel

From the Anse de l'Estaque in the north of the bay outside Marseilles the Rove Canal used to run in a tunnel under the Chaîne de l'Estaque to the Etang de Berre. 22m/72ft wide and 15.4m/50ft high it was the tunnel with the largest cross-section and ships with a draught of up to 4.5m/14ft could use the 7km/4mi long canal. In 1963 it collapsed and has since been closed. From the N568 a path under the railroad line leads to the tunnel entrance.
