It spread to the rest of the Kingdom of León; Toledo, Ávila, Segovia, and later was spread to southern Spain by the Castile, especially Seville and Granada. However, the famous Mudéjar Rooms of the Alcázar of Seville, although often classified as Mudéjar style, are actually closely related to the Moorish Nasrid palace architecture of the Alhambra; the Christian king, Pedro of Castile commissioned Moorish architects from Granada to build them. Centers of Mudéjar art are found in other cities Toro, Cuéllar, Arévalo and Madrigal de las Altas Torres. A separate tradition of Mudéjar style became highly developed in Aragon, with three main focuses at Zaragoza, Calatayud, and Teruel, during the 13th, 14th and 15th centuries. In Teruel a wide group of imposing churches and towers were built. Other fine examples of Mudéjar can be found in Casa de Pilatos in Seville, Santa Clara Monastery in Tordesillas, or the churches of Toledo, one of the oldest and most outstanding Mudéjar centers. In Toledo, the synagogues of Santa María la Blanca and El Tránsito (both Mudéjar though not Christian) deserve special mention. Renaissance In Spain, Renaissance styles began to be grafted onto Gothic forms in the last decades of the 15th century. The forms that started to spread were made mainly by local architects: that is the cause of the creation of a specifically Spanish Renaissance that brought the influence of southern Italian architecture, sometimes from illuminated books and paintings, mixed with the gothic tradition and local idiosyncrasies. The new style was called Plateresque because of the extremely decorated façades that brought to the mind the decorative motifs of the intricately detailed work of silversmiths, the "plateros". Classical orders and candelabra motifs (a candelieri) were combined freely into symmetrical wholes. In that scenery, the Palace of Charles V by Pedro Machuca in Granada was an unexpected achievement in the most advanced Renaissance of the moment. The palace can be defined as an anticipation of the Mannerism, due to its command of classical language and its breakthrough aesthetic achievements. It was constructed before the main works of Michelangelo and Palladio. Its influence was very limited and poorly understood, the Plateresque forms prevailed in the general panorama. As decades passed, the Gothic influence disappeared and the research of an orthodox classicism reached high levels. Although Plateresque is a commonly used term to define most of the architectural production of the late 15th and first
