La Rance Tidal Barrage

< Back

The Rance tidal barrage stretches across the Rance Estuary upstream of St. Malo in Brittany. The barrage was completed in 1967 and generates 544 GWh electricity per annum. In addition, the barrage carries a dual carriageway road and shortened the distance between St. Malo and Dinard from 45 km to 10 km. Access for shipping is provided by locks and a swing bridge on the west bank of the estuary.

The two views below are from French postcards and show a general view of the estuary and a view of the barrage itself from the east bank of the river.
