Italy The Italian Republic or Italy is a southern European country, comprising a boot-shaped peninsula and two large islands in the Mediterranean Sea: Sicily and Sardinia. It shares its nothern alpine boundary with France, Switzerland, Austria and Slovenia. The independent countries of San Marino and the Vatican City are enclaves within Italian territory.

The Apennine mountains form the backbone of this half island, leading north-west to where they join the Alps, the mountain range that then forms an arc enclosing Italy from the north. Here is also found a large alluvial plain, the Po-Venetian plain, drained by the Po River and its many tributaries flowing down from the Alps, Apennines and Dolomites. Other well-known rivers include the Tiber, Adige and Arno.

Its highest point is Mont Blanc (Monte Bianco) at 4,810 m, but Italy is more typically associated with two famous volcanoes: the currently dormant Vesuvius near Naples and the very active Etna on Sicily.
