The Palazzo Normanni is the former residence of the Sicilian kings and viceroys, located on the outskirts of the historical part of Palermo. The most famous part of the palace is the Palatine Chapel.

The first buildings on the site of the Palazzo Normanni belonged to the Phoenicians, then there were ancient Roman fortifications. In the 9th century, the Arabs, who captured Palermo in 875, founded their fortress on the site of the ancient ruins, known as the Palace of the Emirs. In the Arab era, the building was one of the fortresses that controlled Palermo, and the residence of the emirs was located in the city itself - in the current Calsa quarter. In 1072, the Normans captured Palermo, and Robert Guiscard set up his residence in the Palace of the Emirs. His nephew Roger II turned the former Arab fortress into a royal palace. During the 16th-17th centuries, the palace was significantly expanded and rebuilt.

Since 1947, the Regional Assembly, the parliament of the autonomous region of Sicily, has been sitting in the Palazzo Normanni. Currently, the Palatine Chapel is a museum, and on certain days visitors are allowed into the ceremonial halls of the third floor of the palace.
