Castle of Santiago was built in the second half of the 15th century by the 2nd Duke of Medina Sidonia. It was not designed for military or surveillance purposes. Therefore, it can be considered as a demonstration of power of the Duchy. Throughout its history, it has functioned as a ducal fortress and barracks. After almost a century of neglect and suffering serious damage from a fire, it was completely remodelled.

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.
