Rotterdam (/ˈrɒtərdæm/, UK also /ˌrɒtərˈdæm/; Dutch: [ˌrɔtərˈdɑm] (listen)) is a city and municipality in the Netherlands. It is the second-largest Dutch city after the capital Amsterdam, and is located in the province of South Holland, at the mouth of the Nieuwe Maas channel leading into the Rhine–Meuse–Scheldt delta at the North Sea. Its history goes back to 1270, when a dam was constructed in the Rotte, after which people settled around it for safety. In 1340, Rotterdam was granted city rights by the Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 13th-largest in the European Union and the most populous in the country. Located in the west of the Netherlands, Rotterdam is in the centre of the Rijnmond conurbation and lies at the southwest corner of the larger Randstad conurbation. A major logistic and economic centre, Rotterdam is Europe's largest port, and had previously been the largest port of the world for a long time. It has a population of 651 446 as of November 2019 and is home to 180 nationalities. Rotterdam is known for its Erasmus University, its riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction of the city centre in the World War II Rotterdam Blitz has resulted in a varied architectural landscape, including sky-scrapers (an uncommon sight in other Dutch cities) designed by renowned architects such as Rem Koolhaas, Piet Blom and Ben van Berkel. The Rhine, Meuse and Scheldt give waterway access into the heart of Western Europe, including the highly industrialized Ruhr. The extensive distribution system including rail, roads, and waterways have earned Rotterdam the nicknames "Gateway to Europe" and "Gateway to the World". Rotterdam will host the Eurovision Song Contest 2020.
