Monreale (/ˌmɒnriˈæl/; Italian pronunciation: [monreˈaːle]; Sicilian: Murriali[3]) is a town and comune in the Metropolitan City of Palermo, in Sicily, Southern Italy.

It is located on the slope of Monte Caputo, overlooking the very fertile valley called "La Conca d'oro" (the Golden Shell), a production area of orange, olive and almond trees, the produce of which is exported in large quantities.

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.

The façade is characterized by two large towers (one partially destroyed by lightning in 1807) and a portal with Romanesque bronze doors decorated by Bonanno Pisano.

The interior is on the Latin cross plan, divided by ogival arcades, and features fresco cycles executed during the reigns of William II and Tancred of Sicily (c. 1194).
