Satellite images from March 2003 show the Italian Peninsula stretching into the central Mediterranean Sea. The landmass extends from the southern Alps in the north to the sea's edge in the south. Locals call it lo Stivale, which means the Boot. This nickname comes from the shape that resembles a high-heeled boot. Three smaller peninsulas add detail to this outline. Calabria forms the toe of the boot. Salento creates the heel. Gargano acts as the spur on the side.
Mountainous Backbone
The Apennine Mountains run through the center of the region like a spine. These mountains give one of the peninsula's names to the entire area. The range starts near the northern border and continues down toward the southern tip. Touring Club Italiano published details about these physical features in 1957. De Agostini Ed. also documented the geography in their 2004 encyclopedia. The mountains separate the eastern coast from the western coast along most of the length.Active Volcano
Mount Vesuvius stands as the only active volcano on continental Europe within this specific area. It sits near the city of Naples on the western side of the boot. No other active volcanoes exist on the mainland portion of the continent here. The mountain has erupted many times throughout recorded history. Its presence adds geological danger to an otherwise stable landmass. Scientists monitor its activity closely today.Political Divisions
A line drawn from the Magra River to the Rubicon River marks the minimum extent of the territory. This boundary excludes the Po Valley and the southern slopes of the Alps. Three political entities occupy the strict sense of the peninsular area. Italy contains virtually the entire peninsula with 26,140,000 people. San Marino exists as a central-eastern enclave covering 31 square kilometers. Vatican City is an enclave inside Rome spanning just 829 square meters. These microstates hold less than one percent of the total area combined.Geographical Definitions
Northern Italy often gets excluded when defining the Italian Peninsula in general discourse. Some definitions include the northern regions while others stop at the Tuscan-Emilian Apennines. De Agostini Ed. published L'Enciclopedia Geografica in 2004 to clarify these boundaries. Touring Club Italiano released Conosci l'Italia in 1957 with similar geographical data. Insular Italy including Sardinia and Sicily remains separate from the mainland count. The population figures exclude those living outside the defined peninsular borders.
