The geography of Italy includes the description of all the physical geographical elements of Italy. Italy, whose territory largely coincides with the homonymous geographical region, is located in southern Europe and comprises the long, boot-shaped Italian Peninsula crossed by the Apennines, the southern side of Alps, the large plain of the Po Valley and some islands including Sicily and Sardinia. Italy is part of the Northern Hemisphere. Two of the Pelagie Islands are located on the African continent.
Lazio or Latium is one of the 20 administrative regions of Italy. Situated in the central peninsular section of the country, it has 5,714,882 inhabitants and a GDP of more than €212 billion per year, making it the country's second most populated region and second largest regional economy after Lombardy. The capital of Lazio is Rome, which is also the capital and largest city of Italy, and completely encircles Vatican City.
The Apennines or Apennine Mountains are a mountain range consisting of parallel smaller chains extending c. 1,200 km (750 mi) the length of peninsular Italy. In the northwest they join the Ligurian Alps at Altare. In the southwest they end at Reggio di Calabria, the coastal city at the tip of the peninsula. Since 2000 the Environment Ministry of Italy, following the recommendations of the Apennines Park of Europe Project, has defined the Apennines System to include the mountains of north Sicily, a total distance of 1,500 kilometres (930 mi). The system forms an arc enclosing the east of the Ligurian and Tyrrhenian seas.
