Cappella Palatina & the Norman Palace — Palermo's gold-mosaic masterpiece
Step into the 12th-century Palatine Chapel, where every inch of wall and ceiling is wrapped in shimmering Byzantine gold mosaics fused with Arab muqarnas woodwork and Norman stone — routinely called one of the most beautiful interiors on earth. It's a UNESCO site and a 10-minute walk or short cab from the cruise berth, so it fits any port day. Go early: the chapel closes for Sunday Mass (9:30-11:30) and the palace also holds the royal apartments and gardens.
