Château d'Auray

Château d'Auray is a castle ruin in Auray's historic center, with visible remains including a round tower and supporting walls that overlook the river and harbor. The site occupies a position along the waterfront that once formed a key part of medieval town defenses.

The castle was built in 1096 to protect a river crossing and rebuilt in 1201 under Arthur I of Brittany to strengthen its defenses. The site gradually lost its military function and was eventually left in ruins.

The site served as a residence for Breton nobility and hosted significant celebrations that reflected its status in regional power structures. Today, visitors can sense the historical importance this location held for the local ruling classes.

The ruins are located in the old town and can be reached via Rue du Château, which was constructed over the former northern moat. The site is easily accessible on foot and free to visit.

The castle's stones were used in 1558 to build fortifications on the nearby island of Belle-Île after King Henry II ordered the site's dismantling. This shows how medieval structures were recycled for new military purposes.
