Barcelona (English /bɑrsɨˈloʊnə/, Catalan: [bərsəˈɫonə], Spanish: [barθeˈlona]) is the capital of Catalonia and the second largest city in Spain, after Madrid, with a population of 1,620,943 within its administrative limits on a land area of 101.4 km2 (39 sq mi). The urban area of Barcelona extends beyond the administrative city limits with a population of around 4.5 million within an area of 803 km2 (310 sq mi), being the sixth-most populous urban area in the European Union after Paris, London, the Ruhr, Madrid and Milan. About five million people live in the Barcelona metropolitan area. It is also the largest metropolis on the Mediterranean Sea. It is located on the Mediterranean coast between the mouths of the rivers Llobregat and Besòs and is bounded to the west by the Serra de Collserola ridge (512 metres (1,680 ft)).
The Port of Barcelona (Catalan: Port de Barcelona, IPA: [ˈpɔr ðə βərsəˈɫonə]; Spanish: Puerto de Barcelona) has a 2000-year history and great contemporary commercial importance. It is Catalonia's largest port, vying with Tarragona, and Europe's ninth largest container port, with a trade volume of 2.57 million TEU's in 2008. It is also one of the most important ports in the Mediterranean. The port is managed by the Port Authority of Barcelona. Its 7.86 km2 (3 sq mi) are divided into three zones: Port Vell (the Old Port), the commercial/industrial port and the logistics port (Barcelona Free Port). The port is undergoing an enlargement that will double its size by diverting the mouth of the Llobregat river 2 km (1¼ mi) to the south, and slightly pushing back the Llobregat Delta Nature Reserve.
This is not the only port in Barcelona, as there are also two additional yacht harbors / marinas: Port Olímpic and Port Fòrum Sant Adrià to the north.
