Apulia (Italian: Puglia) is a region in southeastern Italy bordering the Adriatic Sea in the east, the Ionian Sea to the southeast, and the Strait of Òtranto and Gulf of Taranto in the south. Its southern portion known as Salento, a peninsula, forms the heel of the Italian "boot". The region comprises 19,345 km² (7,469 square miles), and its population is about 4 million. It is bordered by the other Italian regions of Molise to the north, Campania to the west, and Basilicata to the southwest. It neighbors Greece and Albania, across the Ionian and Adriatic Seas, respectively. The region extends as far north as Monte Gargano, and was the scene of the last stages in the Second Punic War.
