UNESCO: Cappella Palatina

The Palatine Chapel is the royal chapel of the Norman kings of Sicily situated on the first floor at the center of the Palazzo Reale in Palermo, Sicily.

Also referred to as a Palace church or Palace chapel, it was commissioned by Roger II of Sicily in 1132 to be built upon an older chapel (now the crypt) constructed around 1080. It took eight years to build, receiving a royal charter the same year, with the mosaics being only partially finished by 1143.

The sanctuary, dedicated to Saint Peter, is reminiscent of a domed basilica. It has three apses, as is usual in Byzantine architecture, with six pointed arches (three on each side of the central nave) resting on recycled classical columns.

The mosaics of the Palatine Chapel are of unparalleled elegance as concerns elongated proportions and streaming draperies of figures. They are also noted for subtle modulations of colour and luminance.
