Sicily, the largest island in the Mediterranean, sits just under the toe of Italy's boot. Evidence of its rich history remain sites such as the Valley of the Temples, with the impressive ruins of seven Greek temples in the Doric style, still well preserved, and works such as the Byzantine mosaics of the Palatine Chapel, an ancient royal chapel located in Palermo . At the extreme east of the island is Mount Etna, one of the highest active volcanoes in Europe.
