Le château en bref
The fort on Harbour Island (Île Harbour), off Dinard, was built in the 17th and 18th centuries under the direction of the military engineers Vauban and Siméon Garangeau, replacing a simpler redoubt, to protect the entrance to the Rance and defend the port of Saint-Malo. According to legend, the island may have sheltered the original port of Aleth before a supposed maritime disaster in 709. The garrison numbered fewer than ten men in peacetime, rising to ninety in wartime. The fort lost its military use after the liberation of Saint-Malo in August 1944 and fell into disrepair. The island is listed as a natural site, and the fort is listed as a monument historique. Privately owned since 1981, the site was at one time the property of the actor Alain Delon, who was captivated by the maritime fortifications while filming *Les Aventuriers* at Fort Boyard in 1967, before it was resold.
