Vintage Saint-Malo Sweatshirt. Saint-Malo is a port city in Brittany, in France's northwest. Tall granite walls surround the old town, which was once a stronghold for privateers (pirates approved by the king). The Saint-Malo Cathedral, in the center of the old town, is built in Romanesque and Gothic styles and features stained-glass windows depicting city history. Nearby is La Demeure de Corsaire, an 18th-century privateer’s house and museum.
