Castillo de San Felipe was built in 1771 during the reign of Carlos III of Spain for the defense of the littoral. It was disarmed by the French army during the Spanish Independence War. Halfway into the 19th century it was occupied by the special forces in charge of the surveillance of the littoral. During the 20th century was abandoned and repaired between 1990-1991.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
