 Some magnificent examples of the taifa architecture have reached our times, like the Aljafería Palace in Zaragoza, or the small Mosque of Cristo de la Luz in Toledo, later transformed into one of the first examples of Mudéjar architecture.The Almoravids invaded Al-Andalus from North Africa in 1086, and unified the taifas under their power.They developed their own architecture, but very little of it remains because of the next invasion, that of the Almohads, who imposed Islamic ultra-orthodoxy and destroyed almost every significant Almoravid building, together with Medina Azahara and other Caliphate constructions.
