Rotterdam ( , , ; lit. "The Dam on the River Rotte") is the second largest city and municipality in the Netherlands. 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 first, but now to the Rhine instead. 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 2020, it had a population of 651,446 and is home to over 180 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. 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". History Early history The settlement at the lower end of the fen stream Rotte (or Rotta, as it was then known, from rot, "muddy" and a, "water", thus "muddy water") dates from at least 950 CE. Around 1150, large floods in the area ended development, leading to the construction of protective dikes and dams, including Schielands Hoge Zeedijk ("Schieland's High Sea Dike") along the northern banks of the present-day Nieuwe Maas river. A dam on the Rotte was built in the 1260s and was located at the present-day Hoogstraat ("High Street"). On 7 July 1340, Count Willem IV of Holland granted city rights to Rotterdam, whose population then was only a few thousand. Around the year 1350, a shipping canal (the Rotterdamse Schie) was completed, which provided Rotterdam access to the larger towns in the north, allowing it to become a local trans-shipment centre between the Netherlands, England and Germany, and to urbanize. The port of Rotterdam grew slowly but steadily into a port of importance, becoming the
