Monreale is a town and comune in the province of Palermo, in Sicily, Italy. It is located on the slope of Monte Caputo, overlooking the very fertile valley called "La Conca d'oro", famed for its orange, olive and almond trees, the produce of which is exported in large quantities. The town, which has a population of approximately 30,000, is about 15 kilometres inland of Palermo, the capital of the island.
Monreale forms its own archdiocese and is renowned for its Norman-Byzantine cathedral. This has been designated as one of several buildings named in a UNESCO World Heritage Site, a group of nine inscribed as Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale.
