This venerable palace dates to the 9th century but owes its current look (and name) to a major 12th-century Norman makeover, during which spectacular mosaics were added to its Royal Apartments and priceless jewel of a chapel, the Cappella Palatina. Designed by Roger II in 1130, the chapel glitters with stunning gold mosaics, its aesthetic harmony further enhanced by the inlaid marble floors and wooden muqarnas ceiling, a masterpiece of Arabic-style honeycomb carving that reflects Norman Sicily's cultural complexity.
The chapel is Palermo's top tourist attraction. Note that queues are likely, and that you'll be refused entry if you're wearing shorts, a short skirt or a low-cut top. The top level of the palace's three-tiered loggia houses Sicily's regional parliament and the Royal Apartments, including the mosaic-lined Sala dei Venti, and Sala di Ruggero II, King Roger's magnificent 12th-century bedroom. These latter attractions are only open to visitors Friday through Monday.
