Bari (/ˈbɑːri/ BAR-ee, Italian: [ˈbaːri] ; Barese: Bare [ˈbæːrə]; Latin: Barium) is the capital city of the Metropolitan City of Bari and of the Apulia region, on the Adriatic Sea in southern Italy. It is one of the most important economic centres of mainland southern Italy. It is a port and university city as well as the city of Saint Nicholas. The city itself has a population of 315,473 inhabitants, and an area of over 116 square kilometres (45 sq mi), while the urban area has 750,000 inhabitants. Its metropolitan province has 1.2 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 Basilica of Saint Nicholas, the Cathedral of San Sabino (1035–1171) and the Norman-Swabian Castle, 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).
