The castle once dominated the Vilaine River from a rocky spur, controlling a strategic river and land route. It was fortified with moats, gates and towers, and its county belonged to the powerful Rieux family.

Old Port of La Roche-Bernard

Highlight • Settlement

The stones, weathered by time, and the steep alleyways tell the story of this "Small Town of Character," born of the sea and maritime trade. Clinging to the banks of the Vilaine, sometimes built into the rocky slope, old houses and private mansions descend towards the old port. A truly unique urban landscape!
