Rotterdam is the second-largest city and a municipality of the Netherlands. It is located in the province of South Holland, at the mouth of the Nieuwe Maaschannel leading into the Rhine–Meuse–Scheldt delta at the North Sea. Its history goes back to 1270, when a damwas constructed in the Rotte, after which people settled around it for safety. In 1340, Rotterdam was granted city rights by the Count of Holland.

A major logistic and economic centre, Rotterdam is Europe's largest port. It has a population of 633,471 (2017).Rotterdam is known for its Erasmus University, its riverside setting, lively cultural life and maritime heritage. The near-complete destruction of the city centre in the World War II Rotterdam Blitz has resulted in a varied architectural landscape, including sky-scrapers (an uncommon sight in other Dutch cities) designed by renowned 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".

Amsterdam is the capital city and most populous municipality of the Netherlands. Its status as the capital is mandated by the Constitution of the Netherlands, although it is not the seat of the government, which is The Hague. Amsterdam has a population of 851,373 within the city proper, 1,351,587 in the urban area] and 2,410,960 in the metropolitan area. The city is located in the province of North Holland in the west of the country but is not its capital, which is Haarlem. The metropolitan area comprises much of the northern part of the Randstad, one of the larger conurbations in Europe, with a population of approximately 8 million.

On the southern bank of the Waal River lies the city of Nijmegen, a major industrial center where brick manufacturing, the chemical industry, tobacco production, and electrical equipment manufacturing are especially well developed. One of the most curious constructions, shaped like a whale, is located on the Waal's riverbank — it’s the river fleet control center, as Nijmegen also serves as a river port. Nearby stands a sculpture of the fictional heroine Mariken van Nijmegen, who has become a symbolic figure for the city.

Nijmegen is also home to the fascinating National Bicycle Museum “Velorama.” Interestingly, it is the only museum of its kind in the Netherlands, despite the country’s well-known love of cycling. The museum’s exhibitions display the beauty and diversity of bicycle transport. Today, its collection includes over 500 bicycles.
