October 9, 2025, Tour de l'Horloge de Dinan

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.

It's a shame there isn't a cycle path at the marsh bridge, because getting down isn't easy at all.
