Vauban citadel on Belle Île
Built in 1549, the citadel was enlarged over the years, most notably by Vauban. Among other functions, it was a prison. Abandoned by the army, it was sold in 1960 to private owners. The Historical Museum is now housed in the casemates. Note the circular powder magazine, the large arsenal, where exhibitions are held, and the dungeons. The Bastion de la Mer and Bastion du Dauphin afford remarkable views.
