The Cathedral of Mionreale, outside of Palermo Italy, was built in 1184 after Sicily was taken back from the Saracens by the Norman Crusaders. King William II of Sicily had the cathedral built on the site where the archbishop of Palermo had been exiled to during the reign of the Saracens from around 800 AD to 1072 AD.
In commemoration he had a church built with interior walls covered in mosaics made of gold leaf tiles. The mosaics tells many of the stories of the old and new testaments.
