Cappella Palatina (Palatine Chapel), Palermo

The Cappella Palatina, the royal chapel of the Norman kings of Sicily, occupies the first floor of the Palazzo dei Normanni (the Norman Palace) in the heart of Palermo. Commissioned by King Roger II, it was begun around 1132 and consecrated in 1140, with its decoration continuing through the following decades. The chapel is the most celebrated monument of the Arab-Norman culture that flourished in 12th-century Sicily, where Latin Christian, Greek Byzantine and Arab Islamic traditions met and merged under Norman rule. Its plan combines a Latin basilica of three aisles divided by ancient granite and marble columns with a Byzantine domed sanctuary at the east end. The walls and dome glow with golden mosaics executed by Byzantine craftsmen, depicting Christ Pantocrator in the cupola and apse, scenes from the Old and New Testaments, and ranks of saints and angels, forming one of the richest and best-preserved mosaic programmes of the medieval Mediterranean. Equally extraordinary is the wooden ceiling of the nave, a muqarnas (stalactite or honeycomb) structure carved and painted by Muslim artists in the Fatimid style, decorated with figures, animals and inscriptions in Arabic, widely regarded as the finest such ceiling outside the Islamic world. The chapel's floors and lower walls are clad in opus sectile marble inlay, and a tall paschal candlestick and a marble ambo complete an interior of exceptional unity. Restoration campaigns, including a major cleaning of the mosaics and ceiling completed in the 2000s, have returned the chapel to remarkable brilliance. The Cappella Palatina remains a consecrated space within an active seat of the Sicilian regional assembly, and it stands as the defining image of the religious tolerance and artistic synthesis that made Norman Palermo one of the great cultural capitals of its age.
