Rotterdam is the second-largest city in the Netherlands by population and the largest by area (319.4 km2). 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.
