The Bidouane Tower is a historic gunpowder tower at the northwestern tip of the city walls, built in the 15th century for the defense of the city. In 1693, an attack by Anglo-Dutch forces on the tower failed when a ship loaded with explosives ran aground prematurely. In 1889, the tower lost its military function and today serves as a lookout point with panoramic views of the Bay of Saint-Malo, the islands of Grand Bé and Petit Bé, and the coast as far as Cap Fréhel.
