World's first tidal power station
The tidal power plant reportedly attracts 200,000 visitors per year. A canal lock in the west end of the dam permits the passage of 16,000 vessels between the English Channel and the Rance. The display centre is looking a bit tired and there isn't much to see from the barrage wall. Getting there is a bit tricky, bus routes C1 and C2 get you to within a kilometer walk.
