Grottes du Régulus

The Grottes du Régulus are a cave network carved into limestone cliffs that rise above the Gironde estuary, extending roughly 30 meters above the water. The various chambers are distributed throughout the rock face and create a complex underground system.

During the 16th century Religious Wars, these caves provided shelter for Protestant communities to practice their faith. This early use established the caves as a place of refuge during times of conflict.

The caves are named after a French warship that was deliberately sunk in 1814 to prevent English forces from capturing it. This name connects the location to a dramatic episode of naval history.

Access to the caves is straightforward, with stairs and paths guiding visitors through the different chambers carved into the rock. Wearing comfortable shoes is advisable, and visitors should check the opening times before planning their visit.

The different chambers still bear traces of their various uses across different periods, from storage areas to living quarters. Visitors can observe how each space was adapted for its specific purpose at the time.
