A monumental stone battleship rising from the ocean
Conceived under Louis XIV and completed under Napoleon III in 1857 to protect the naval arsenal of Rochefort against British attack, Fort Boyard is an astonishing naval engineering feat. Measuring 68 metres long and 20 metres high, its oval limestone hull was built upon a treacherous sandbank in open ocean waters.
While internal access is closed to the public due to its use as a television game show set, circling the colossal walls by sea reveals its raw power. Gazing up at the granite gunports and watchtowers as Atlantic waves break against the breakwater delivers an unforgettable maritime spectacle.
What to expect on a Fort Boyard cruise

The approach across the Pertuis d'Antioche
Cross the strait between Île de Ré and Île d'Oléron, spotting oyster beds and seabirds as the distinctive silhouette of the fort grows on the horizon.
Close-up circumnavigation
The vessel circles slowly within metres of the sea-worn limestone foundations, providing 360-degree photo opportunities and commentary on its construction.
