Palermo Cathedral is the cathedral church of the Roman Catholic Archdiocese of Palermo, located in Palermo, Sicily, southern Italy. It is dedicated to the Assumption of the Virgin Mary. As an architectural complex, it is characterized by the presence of different styles, due to a long history of additions, alterations and restorations, the last of which occurred in the 18th century. History The church was erected in 1185 by Walter Ophamil, the Norman archbishop of Palermo and King William II's minister, on the area of an earlier Byzantine basilica. By all accounts this earlier church was founded by Pope Gregory I and was later turned into a mosque by the Saracens after their conquest of the city in the 9th century. Ophamil is buried in a sarcophagus in the church's crypt. The medieval edifice had a basilica plan with three apses, of which only some minor architectural elements survive today. The upper orders of the corner towers were built between the 14th and the 15th centuries, while in the early Renaissance period the southern porch was added. The present neoclassical appearance dates from the work carried out over the two decades 1781 to 1801, supervised by Ferdinando Fuga and Giuseppe Venanzio Marvuglia. During this period the great retable by Gagini, decorated with statues, friezes and reliefs, was destroyed and the sculptures moved to different parts of the basilica. Also by Fuga are the great dome emerging from the main body of the building, and the smaller domes covering the aisles' ceilings. Overview The western entrance is on the current Via Matteo Bonello, and has the appearance set in the 14th and 15th centuries. It is flanked by two towers and has a Gothic portal surmounted by a niche with a precious 15th-century Madonna. Two lintelled ogival arcades, stepping over the street, connect the western façade to the bell tower, which is annexed to the Archbishops Palace (now Museo Diocesano). This has a squared appearance adorned in the upper part by a fine crown of smaller belfries and small arcades. The south side has outstretching turrets and a wide portico (the current main entrance) in Gothic-Catalan style, with three arcades, erected around 1465 and opening to the square. The first column on the left belonged to the original basilica and the subsequent mosque, as testified by the Qur'an verse carved on it. The carved portal of this entrance was executed in
