Saint-Martin-de-Ré is a port town on the Île de Ré, an island off the west coast of France. Cafes and restaurants with outdoor terraces surround the busy harbor. It’s ringed by star-shaped, 17th-century ramparts, drawn up by Vauban between 1681 and 1685. The Saint-Martin church, built in the 15th century, dominates the landscape. Ernest Cognacq Museum, located on the Ile de Re, is a must-visit destination for history enthusiasts.
