Italy (geographical region)

The Italian geographic region, Italian physical region or Italian region is a geographical region of south-central Europe delimited to the north by the mountain chains of the Alps. This subregion is composed of a peninsular and continental part and an insular part. Located between the Balkan Peninsula and the Iberian Peninsula, it protrudes into the centre of the Mediterranean Sea and overlooks the Adriatic Sea, the Ionian Sea, the Ligurian Sea, the Sardinian Channel, the Sea of Corsica, the Sea of Sardinia, the Strait of Sicily, and the Tyrrhenian Sea. The Italian geographic region, in its traditional and most widely accepted extent, has an area of approximately , which is greater than the area of the entire Italian Republic (). The region also includes territories that are sovereign parts of Croatia, France, Slovenia, and Switzerland, as well as the four small sovereign states of the Principality of Monaco, the Republic of Malta, the Republic of San Marino, and the Vatican City State (the Holy See). In common language, the Italian region generally refers to the Italian Peninsula. Similarly, the inhabitants of the islands use the term continent to designate the mainland that goes from the Alps to Reggio Calabria. Geographically, Italy running in north-west to south-east direction can be divided into the calcareous Alps, the alluvial plain, the Northern, Central and Southern Apennines and Sicily. The natural limits of the Italian region, marked by the Alpine drainage divide and the sea, are relatively clear, except at the western and eastern extremities of the Alps. On the eastern borders, the chain of the Julian Alps and the Kvarner Gulf are traditionally indicated, to which Dante Alighieri also refers. However, other proposed limits include a border along the Isonzo (formerly advocated by Austrian Empire), which would exclude the upper Isonzo valley, Trieste and Istria entirely.
