Saint-Malo is a port city in Brittany, northwest of France. High granite walls surround the old town, which was once a bastion for privateers (pirates approved by the king). The cathedral of Saint-Malo, in the center of the old town, has Romanesque and Gothic styles, and has stained glass windows telling the history of the city. The nearby Demeure de Corsaire is an 18th-century privateer’s house. It is now a museum.
