Arévalo castle was built in the 14th century and reformed during the 15th and 16th centuries. It has a pentagonal ground plan and a large Tower of Homage. Inside there is a Cereal Museum.
King Pedro I, the Cruel, locked his wife Blanca de Borbón in the castle. Juan II and Enrique IV possessed it, the latter handed it to don Álvaro de Zúñiga; between 1476 and 1480, Zúñiga and the Catholic Monarchs negotiated a compesation for Arévalo and, in the ends, the village was taken over by the Crown. Subsequently it became a state prison.

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.
