Fort Boyard, Sea fortress in Île-d'Aix, France

The oval-shaped stone fortress rises 20 meters above sea level between the islands of Oléron and Aix in the Pertuis d'Antioche straits.

Military engineers constructed this defensive structure between 1801 and 1857 to protect the arsenal of Rochefort from British naval attacks.

The Department of Charente-Maritime transformed this former military fortress into a television production location, hosting game shows since 1990.

Maritime excursions depart from Fouras-les-Bains, Rochefort, and Port-des-Barques, allowing visitors to circle the fortress and observe its architecture.

The fortress stands on a sandbank that remained submerged under 4.5 meters of water during low tide, requiring extensive engineering solutions.

What to see on Oléron Island: tourist sites, historical monuments, and beaches to visit

Oléron Island, the largest island in mainland France after Corsica, features a military, maritime, and natural heritage reflecting its strategic position facing the Atlantic Ocean. This Charente island, connected to the mainland since 1966 by a nearly three-kilometer-long bridge, houses fortifications built under Louis XIV, such as the Citadel of Château d'Oléron and Fort Louvois, as well as the famous Fort Boyard positioned on its sandbank offshore. The Chassiron Lighthouse, standing at forty-six meters high, marks the northern tip of the island and guides ships through the waters of the Pertuis d'Antioche. Beyond its defensive legacy, the island offers various natural areas where sandy beaches, pine forests, and salt marshes alternate. Saint-Trojan-les-Bains extends its wooded shoreline to the south, while Boyardville features a protected coast on its eastern side. Visitors also observe oyster farming along the La Baudissière channel and explore the colorful huts that house artist workshops at the port of Château d'Oléron. The Saltworks Museum traces the history of salt extraction, a resource that shaped the local economy for centuries.
