Formusson lock, Daon
The Formusson dam is shaped like a chevron. The masonry parts of the lock are made of cut granite. The lock house was built according to the model used throughout the lower Mayenne. It was extended to the south by a bay copied from the original side bays, which replaced the bread oven. There is a well in the garden.
