Córdoba -The Grand Mosque and the Great Cathedral, Spain (128/418)

Cordoba's glorious period began in the 8th century when, conquered by the Moors, some 300 mosques, innumerable palaces and public buildings were constructed to rival the splendours of Constantinople, Damascus and Baghdad. In the 13th century, under Ferdinand III the Saint, Cordoba's Great Mosque was turned into a Cathedral and new defensive structures, particularly the Alcazar de los Reyes Cristianos and the Torre Fortaleza de la Calahorra, were erected.
