This rock, topped with a sentry box, was used in the past to monitor enemy incursions from the small islands in the bay of Port-Blanc.
Having been destroyed, the gatehouse was rebuilt at the beginning of the 20th century on the initiative of Théodore Botrel. He added two statues: that of Saint-Tugdual and that of Our Lady of the Sea.

Port-Blanc Harbor

Highlight • Structure

This fishing port is also a seaside resort. Tombstones (now covered again) were discovered under the dunes of the main beach, suggesting the existence of a necropolis.
