To the south it consists of the entirety of the Italian Peninsula, Sicily, Sardinia—the two largest islands in the Mediterranean Sea—and many other smaller islands. The independent states of San Marino and the Vatican City are enclaves within Italy, whilst Campione d’Italia is an Italian exclave in Switzerland.
