Sicily is full of superlatives, many of them relating to treasures of the ancient world. In Agrigento's Valley of Temples, for example, you'll see one of the three most perfect temples in the Greek world. At Selinunte is one of the largest of all known Greek temples. Villa Romana del Casale in Enna, with more than 3,500 square meters of mosaics, is one of the best-preserved villas anywhere in the Roman Empire and now a UNESCO World Heritage Site.

So are the twin towns of Ragusa and Modica for representing Europe's zenith of Baroque art. Both the stunning mosaics and the exquisite cloister at Monreale are considered highlights of European art, and the collections at Palermo's Archeological Museum rank it as one of Italy's best.
