The Palacio de los Duques del Infantado was built at the end of the 15th Century in the Isabelline style. It was the residence of the Mendoza dynasty and above the doorway is the family crest. The palace boasts a splendid decorated facade and the upper gallery has pairs of ogee windows. On the columns of the patio are Mudejar decorations. During the Civil War the interior was damaged, but it has since been restored and is now the home of the Provincial Museum.
