Arab-Norman Palermo and the Cathedral Churches of Cefalú and Monreale is a series of nine religious and civic structures located on the northern coast of Sicily dating from the era of the Norman Kingdom of Sicily : two palaces, three churches, a cathedral, a bridge are in Palermo, as well as the cathedrals of Cefalú and Monreale.
The new Norman rulers started to build various constructions in what is called the Arab-Norman style. They incorporated the best practices of Arab and Byzantine architecture into their own art.
