Owing to the gradual conquests by the Christians of towns belonging to the Muhammadans, several of them continued to be inhabited by Moors, who kept their customs and religion. They were called Moriscos or Mudejares. The chief industries of the country were in their hands, and several churches and other buildings of importance were built by them. They accommodated their architecture to European or Christian necessities, and created a new style (Mudejar), a mixture of Christian and Moorish art, which is only to be found in the Spanish Peninsula. The finest specimens are of the fourteenth century. The religious constructions of this period are remarkable for their brickwork in towers and apses, and fine wooden ceilings, artesonados. Examples exist at Toledo, Seville, and Granada. The interesting synagogues built by Moriscos are at Toledo and Segovia. As specimens of civil architecture, the finest are Casa de Pilatos (Seville), Palace of Mendoza (Guadalajara), Archbishop’s Palace (Alcalá), Casa de Mesa (Toledo). This style continued in vogue during the greater part of the sixteenth century, although late Gothic was everywhere predominant. A most striking example in which the three styles--Moorish, Flamboyant, and Renaissance--are combined, is to be found in a chapel of the cathedral of Sigüenza. The Romanesque style of architecture was imported in the eleventh and twelfth centuries from France, even more directly than in other countries, owing to the immense influence exercised by a large number of prelates and priests, who came from Cluny and Cister, and the French princes and families who settled in Spain. The general features of this architecture are similar to those of France: the differences exist chiefly in the general plan of the churches rather than in their construction and ornamentation. The choirs in Spanish cathedrals are placed in the central nave, a traditional remembrance of the early basilica. In some localities, Segovia, Avila, and Valladolid, some of these churches have external cloisters, an Oriental or Italian modification, which never occurs in France or the north of Europe. Romanesque examples are very numerous in Spain. Some, such as the doorway of the Cathedral of Santiago (Galicia), and the Old Cathedral (Salamanca), are not surpassed by any similar buildings in Europe. Specimens are only found in the northern provinces, as the south was not conquered from the Moors until the thirteenth century. Interesting examples exist in Asturias, Galicia, Castile, Aragon, and Cataluña. The cloisters of Gerona and Tarragona are unrivaled. Of the many striking examples of Transition from Romanesque to Early Pointed, the finest are the old cathedral of Lerida, the cathedrals of Tarragona and Santiago, and the collegiate church of Tudela.
