Rotterdam (/ˈrɒtərdæm/ ROT-ər-dam, UK also /ˌrɒtərˈdæm/ ROT-ər-DAM,[8][9] Dutch: [ˌrɔtərˈdɑm] ⓘ; lit. "The Dam on the River Rotte") 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.

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" (Wikipedia)
