The world's most comprehensive and exquisite set of Roman mosaics is found in the middle of Sicily, at the archaeological site known as Villa Romana del Casale. The specifics of the villa's history are largely lost to history, but experts have dated its origin to around the 4th century AD. It's believed to have been the hunting lodge for Roman aristocrats, possibly owned by Emperor Maximianus Herculius. But there aren't enough clues to say for certain.
One of the top sights in Palermo is the Norman Palace, on the western extreme of the old city center. A massive complex built in the 11th century, the palace is still used today as the seat of the Sicilian government. Tourists are allowed in, but understandably restricted to a small section.
Entrance to Monreale's mind-shattering Cathedral was free, so when the ticket lady at the neighboring Benedictine Cloister asked us for €6 apiece, we were expecting to be blown away. Unfortunately, we weren't.
If you don't want your jaw to smack painfully against the ground, you'd do well to wear a tight chin strap when visiting the Cathedral of Monreale. During our tour, my mouth was wide open, rivulets of drool escaping my gaping jowl. But I didn't care, and I doubt anyone was paying attention. To be inside the Monreale's cathedral and concentrate on anything other than its shimmering beauty is nearly impossible.
