of Spanish pre-Romanesque styles, mainly Asturian and Mozarabic, but there is also a strong Moorish influence, especially the vaults of Córdoba's Mosque, and the multifoil arches. In the 13th century, some churches alternated in style between Romanesque and Gothic. Aragón, Navarra and Castile-Leon are some of the best areas for Spanish Romanesque architecture. Gothic The Gothic style arrived in Spain in the 12th century. In this time, late Romanesque alternated with a few expressions of pure Gothic architecture like the Cathedral of Ávila. The High Gothic arrived in all its strength through the Way of St. James in the 13th century, with some of the purest Gothic cathedrals, with French and German influences: the cathedrals of Burgos, León and Toledo. The most important post-13th century Gothic styles in Spain are the Levantine and Isabelline Gothic. Levantine Gothic is characterised by its structural achievements and their unification of space, with masterpieces as La Seu in Palma de Mallorca; the Valencian Gothic style of the Lonja de Valencia (Valencia's silk market), and Santa Maria del Mar (Barcelona). Isabelline Gothic, created during the times of the Catholic Monarchs, was part of the transition to Renaissance architecture, but also a strong resistance to Italian Renaissance style. Highlights of the style include the Monastery of San Juan de los Reyes in Toledo and the Royal Chapel of Granada. Mudéjar Mudéjar style or art is Christian architecture with Islamic influenced decoration that emerged in the Christian kingdoms of the north in the 12th century and spread with the Christian reconquest of the Iberian Peninsula. The reconquest brought Moorish craftsmen under Christian rule who then influenced architecture in the expanding Christian kingdoms. It is not a style of architecture; Mudéjar style refers to the application of Moorish style decorations or materials to whatever Christian architecture existed at the time, producing Mudéjar-Romanesque, Mudéjar-Gothic and Mudéjar-Renaissance. Mudéjar art influenced Christian architecture through Islamic and Jewish constructive and decorative methods and was highly variable from region to region. Mudéjar is characterised by the use of brick as the main building material. The dominant geometrical character, distinctly Islamic, emerged conspicuously in the accessory crafts using cheap materials elaborately worked – tilework, brickwork, wood carving, plaster carving, and ornamental metals. Even after the Muslims were no longer employed, many of their methods and decorative styles continued to be applied to Spanish architecture. Mudéjar style was born in the northern town of Sahagún.
