It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.

A beautiful church with magnificent stained-glass windows and lovely statues. Its interior is unfortunately a little dark. Its restoration has enhanced its appeal.

The dam itself is interesting, but the route is not ideal for cyclists.

Closed chapel. Built at the beginning of the 20th century. Very beautiful gable with its "Cornouaillais" bell tower and its beautiful gargoyles.
