Palacio de Monterrey (Monterrey Palace), one of the best examples of Plateresque style in Spain, begun in 1539. It was designed by Rodrigo Gil de Hontañón and Martín de Santiago. It has a quadrangular plan, with towers on the corners and a central court. At the corners are sculptures of lions and imaginary animals, keeping the coat of arms of the Zúñiga, Acevedo, Ulloa and Fonseca families. In the interior are two landscape paintings by Jusepe de Ribera (1639), and a Jason with the Dragon by Salvator Rosa. The palace is currently owned by the House of Alba.
