Monreale Cathedral (Italian: Cattedrale di Santa Maria Nuova di Monreale; Duomo di Monreale) is a Catholic church in Monreale, Metropolitan City of Palermo, Sicily. One of the greatest existent examples of Norman architecture, it was begun in 1174 by William II of Sicily. In 1182 the church, dedicated to the Nativity of the Virgin Mary, was, by a bull of Pope Lucius III, elevated to the rank of a metropolitan cathedral as the seat of the diocese of Monreale, which was elevated to the Archdiocese of Monreale in 1183. Since 2015 it has been part of the Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale UNESCO World Heritage Site.
The church is a national monument of Italy and one of the most important attractions of Sicily. Its size is 102 meters (335') long and 40 meters (131') wide.
