The favourite residence of the Dukes of Brittany, this imposing château stands close to the sea. Built in the 13C and remodelled in the 14C and 15C, it was confiscated by François I. Since the site was used as a stone quarry during the Revolution, only six of its towers remain, but it has been patiently restored. In the first rooms you come to, take note of the exceptional glazed ceramic floors, which are a fine example of medieval decorative art. The ceremony hall leads out to the terraces, which afford beautiful panoramic views over the peninsula and the ocean that lies close by.
