Rotterdam 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. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2022, it had a population of 655,468 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.
