Rotterdam is the second-largest city in the Netherlands after the national capital of Amsterdam. It is in the province of South Holland, part of the North Sea mouth of the Rhine-Meuse-Scheldt delta, via the "New Meuse" inland shipping channel, dug to connect to the Meuse at first and now to the Rhine.
Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam-The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country.
A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2022, Rotterdam had a population of 655,468 and is home to over 180 different nationalities.
Rotterdam is known for its university, 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 skyscrapers designed by architects such as Rem Koolhaas, Piet Blom and Ben van Berkel.
