FORT CLONQUE

On the edge and off the coast of the bay of the same name, this military building is set on a rocky spur and is connected to the coast by a causeway covered at high tide. Its architect, William Jervois, wanted to respect the environment and tried to blend its fortifications into the landscape from the 19th century. It has since been transformed into apartments, which you can rent if you wish. Also worth seeing is Fort Tourgis, another hillside barracks, much more showy and also built in the mid-nineteenth century.
