A pretty little peaceful port on the banks of the Rance. The road, however, is certainly less peaceful in season 😅.

The Tour de l'Horloge on Rue de l'Horloge is a medieval bell tower dating back to the late 15th century. Originally serving as a watchtower and town hall, it now houses a small museum. At 40 meters high and with 158 steps, it offers impressive panoramic views of the Old Town, the surrounding area, and, on a clear day, even as far as Mont Saint-Michel.
