Saint-Malo: A Town of Fascinating History

Founded by the Welsh monk Mac Low, the old walled town of Saint-Malo is protected by its ramparts, the oldest dating from the 12th century. Walk in the footsteps of fascinating characters such as Chateaubriand, Surcouf, Jacques Cartier, or Anne of Brittany.

Visit the castle museum, built by the Dukes of Brittany in the 15th century, the Hôtel Asfeld, and the cathedral, then stroll along the beach to see the Fort National and the tiny islands of Grand Bé and Petit Bé—accessible only at low tide. Enjoy a shopping trip to the walled town full of small shops and sunny terraces, then the charm of a stroll along the ramparts, and make the most of the fresh sea air as you return by foot along the beach.
