During the Islamic rule, particularly in the year 844, the city was razed by the Vikings, and the walls were burned down. After that the emir Abderramán II, fourth Umayyad Emir of Córdoba (822–852) rebuilt the walls, which were again destroyed by his great grandson Abd-ar-Rahman III, eighth independent emir (912–929) and first Umayyad caliph of Córdoba (929–961).
