Citadelle Vauban & Musée d'Art et d'Histoire Golfe Du Morbihan

The dramatic citadel, strengthened by the architect Vauban in 1682, dominates little Le Palais port. Inside, the informative museum's displays concentrate on the history of the island's defensive system, though there are also sections on the local fishing trade and island life. There's also a very smart hotel here and a restaurant.
