This is one of the finest existing examples of Spanish Renaissance architecture and you'll find it in the pretty little Plaza de Monterrey. It rivals the royal palaces in Seville in terms of beauty. It was built for the aristocratic Monterrey family in 1539 by the architect, Rodrigo Gil de Hontañón and now belongs to the Alba family. The exterior is eye-catching: the two towers bear coats-of-arms belonging to noble families like the Fonseca, Zúñiga and Maldonado. Even the chimneys are outstanding works of art and display family shields in the corners.

It is not open to the public.
