Brescou Fort
About one kilometer off the coast of Cap d'Agde lies the Fort de Brescou on the island of the same name. It was built in the 16th century for defense against the Spanish conquerors and later served as a state prison. The fortress seems to be fused with the rocks of the islands. Even today, the four bastions of the castle can be seen. In front of one of them stretches a small sandy beach. Besides the fort, there are also two lighthouses on the island.
