Belle-Ile is an island off the coast of Brittany in northwest France. In the main town La Palais, Citadelle Vauban is a star-shaped fortress. The fort at Pointe des Poulains, the island's northern tip, houses a museum dedicated to 19th-century actress Sarah Bernhardt. Sandy Donnant Beach lies on the rugged west coast. Nearby, the Grand Phare lighthouse looks out over the needles rock formations of Port-Coton.
