The Fort du Grand Bé and Fort du Petit Bé are two historic fortifications located off the coast of Saint-Malo, each playing a significant role in the city’s maritime defenses.

The Fort du Grand Bé sits on a tidal island accessible only at low tide. Built in the 17th century, it was part of Saint-Malo’s coastal defense system, designed to protect the city from naval attacks. Today, the island is best known as the final resting place of François-René de Chateaubriand, the famous French writer and diplomat. Visitors can walk to the island when the tide permits, enjoying panoramic views of the walled city and the surrounding coastline.

The Fort du Petit Bé, constructed by Vauban in the 17th century, is located just beyond Grand Bé and was designed to reinforce Saint-Malo’s defenses. Unlike Grand Bé, Petit Bé remains a fully restored fort, offering guided tours that explore its military history and strategic importance. The fort was equipped with 19 cannons, capable of repelling enemy ships attempting to breach the city’s defenses. Accessible by foot at low tide or by boat, it provides a fascinating glimpse into Saint-Malo’s fortified past.

Both forts contribute to the city’s rich maritime heritage, offering visitors a chance to explore Saint-Malo’s defensive ingenuity while enjoying breathtaking coastal scenery. Whether visiting for history or the stunning views, these sites are essential stops for anyone exploring the region.
