Forts in Quiberon

Historic Fortifications

This collection highlights the defensive heritage of the Quiberon peninsula and the Morbihan islands. Spanning from the 17th to the 19th centuries, these structures include Vauban-style citadels, coastal guardhouses, and 19th-century "réduits" designed to protect the French coast from naval incursions. Key sites include the imposing Citadelle at Belle-Île-en-Mer and the strategic Fort de Penthièvre, which controls the narrow isthmus. Visitors can explore a variety of military architecture, from fortified manors to rugged island outposts.
