Bari listen (help·info) (Bari dialect: Bare; Latin: Barium; Ancient Greek: Barion) is the capital city of the province of Bari and of the Apulia (or, in Italian, Puglia) region, on the Adriatic Sea, in Italy. It is the second most important economic centre of mainland Southern Italy after Naples, and is well known as a port and university city, as well as the city of Saint Nicholas. The city itself has a population of about 320,475, as of 2011, over 116 km2, while the fast-growing urban area counts 653,028 inhabitants over 203 km2. The metropolitan area counts 1 million inhabitants.
Bari is made up of four different urban sections. To the north is the closely built old town on the peninsula between two modern harbours, with the splendid Basilica of Saint Nicholas, the Cathedral of San Sabino (1035–1171) and the Swabian Castle built for Frederick II, which is now also a major nightlife district. To the south is the Murat quarter (erected by Joachim Murat), the modern heart of the city, which is laid out on a rectangular grid-plan with a promenade on the sea and the major shopping district (the via Sparano and via Argiro).
It has an area of 5,138 km2 (1,984 sq mi), and a total population of 1,594,109 (2005). There are 48 comuni (singular: comune) in the province, see Comuni of the Province of Bari. However, in the year 2009 the new Province of Barletta-Andria-Trani was created, taking with it seven of these comuni with a total population of 346,025. (The other three comuni of the new province will come from the Province of Foggia.) This would leave the remaining Province of Bari with 41 comuni and an adjusted population of 1,248,084 as of the 2005 census. .
