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.

Milestone marking the boundary of the Abbey of Prières. Created between 1248 and 1252, it was located in Billiers, near the Pointe de Penlann. The abbey was largely destroyed during the Revolution. There are still a few buildings, the bell tower and a few milestones at the boundary of its domain. This milestone is the easiest to find: it is decorated with a Macle (heraldic symbol) and an Ermine (symbol of the Dukes of Brittany who founded the abbey).
