Rotterdam in the context of HSL-Zuid

The Randstad (Dutch pronunciation: [ˈrɑntstɑt] ; "Rim City" or "Edge City") is a roughly crescent- or arc-shaped conurbation in the Netherlands, that includes almost half the country's population. With a central-western location, it connects and comprises the Netherlands' four biggest cities (Amsterdam, Rotterdam, The Hague, and Utrecht), their suburbs, and many towns in between, that all grew and merged into each other. Among other things, it includes the Port of Rotterdam (the world's busiest seaport outside Asia), the Port of Amsterdam (Europe's fourth-busiest seaport), and Amsterdam Airport Schiphol (Europe's fourth-busiest airport). With a population of approximately 8.4 million people it is one of the largest metropolitan regions in Europe, comparable in population size to the Rhine-Ruhr metropolitan region or the San Francisco Bay Area, and covers an area of approximately 11,372 km (4,391 sq mi). The Randstad had a gross regional domestic product of €510 billion in 2022, making it the second most productive region in the European Union, only behind the Paris metropolitan area. It encompasses both the Amsterdam metropolitan area and Rotterdam–The Hague metropolitan area. It is part of the larger Blue Banana megalopolis.

The Randstad's main cities are Almere, Amsterdam, Delft, Dordrecht, Haarlem, The Hague, Leiden, Rotterdam, and Utrecht. Other cities and towns include Alkmaar, Alphen aan den Rijn, Amersfoort, Amstelveen, Capelle aan den IJssel, Gouda, Heerhugowaard, Hilversum, Hoofddorp, Hoorn, Lelystad, Nieuwegein, Purmerend, Rijswijk, Schiedam, Spijkenisse, Vlaardingen, Zaandam, Zeist, and Zoetermeer.

A local ordinance is a law issued by a local government such as a municipality, county, parish, prefecture, or the like.

The Rhine–Main–Danube Canal (German: Rhein-Main-Donau-Kanal; also called Main-Danube Canal, RMD Canal or Europa Canal) is a canal in Bavaria, Germany. Connecting the Main and the Danube rivers across the European Watershed, it runs from Bamberg via Nuremberg to Kelheim. The canal connects the North Sea and Atlantic Ocean to the Black Sea, providing a navigable artery between the Rhine delta (at Rotterdam in the Netherlands), and the Danube Delta in south-eastern Romania and south-western Ukraine (or Constanța, through the Danube–Black Sea Canal). The present canal was completed in 1992 and is 171 kilometres (106 mi) long.

The Turks in Europe (sometimes called Euro-Turks; Turkish: Avrupa'daki Türkler or Avrupa'da yaşayan Türkler or Avrupa Türkleri) refers to Turkish people living in Europe.

Generally, "Euro-Turks" refers to the large Turkish diasporas living in Central and Western Europe as well as the Turkish communities in the former Ottoman Empire and those living in Russia and other European Post-Soviet states. When the term "Euro-Turks" is taken in its most literal sense, Turkish people living in the European portion of Turkey are also included in the term. Even more broadly, the Turkish Cypriot community for people living in Cyprus, which is located in Asia, has also been defined under the term "Euro-Turks" since the island joined the European Union.

The Port of Rotterdam is the largest seaport in Europe, and the world's largest seaport outside of Asia, located in and near the city of Rotterdam, in the province of South Holland in the Netherlands. From 1962 until 2004, it was the world's busiest port by annual cargo tonnage. It was overtaken first in 2004 by the port of Singapore, and since then by Shanghai and other very large Chinese seaports. In 2020, Rotterdam was the world's tenth-largest container port in terms of twenty-foot equivalent units (TEU) handled. In 2017, Rotterdam was also the world's tenth-largest cargo port in terms of annual cargo tonnage.

Covering 105 square kilometres (41 sq mi), the port of Rotterdam now stretches over a distance of 40 kilometres (25 mi). It consists of the city centre's historic harbour area, including Delfshaven; the Maashaven/Rijnhaven/Feijenoord complex; the harbours around Nieuw-Mathenesse; Waalhaven; Vondelingenplaat; Eemhaven; Botlek; Europoort, situated along the Calandkanaal, Nieuwe Waterweg and Scheur (the latter two being continuations of the Nieuwe Maas); and the reclaimed Maasvlakte area, which projects into the North Sea. The Port of Rotterdam is located in the middle of the Rhine-Meuse-Scheldt delta. Rotterdam has five port concessions (ports) within its boundaries—operated by separate companies under the overall authority of Rotterdam.

The Rotterdam–The Hague metropolitan area (Dutch: Metropoolregio Rotterdam Den Haag) is a metropolitan area encompassing the cities of Rotterdam and The Hague as well as 21 other municipalities. It was founded in 2014. The area has a population of approximately 2.7 million across 1,130 km (440 sq mi). It is the largest European port, with many international organizations residing within its borders.

The area lies in the zuidvleugel (English: "South Wing") of the larger conurbation called Randstad. Air traffic is supported by Rotterdam-The Hague Airport offering services to a number of European cities; however, the majority of air travelers use Amsterdam Airport Schiphol, which is about 45 kilometers from The Hague. Light rail public transport in the area is offered by RandstadRail, Rotterdam Metro, The Hague tram, and Rotterdam tram, heavy rail public transport is provided by the Dutch railways.

Delft (Dutch pronunciation: [ˈdɛl(ə)ft] ) is a city and municipality in the province of South Holland, Netherlands. It is located between Rotterdam, to the southeast, and The Hague, to the northwest. Together with them, it is a part of both the Rotterdam–The Hague metropolitan area and the Randstad.

Delft is a popular tourist destination in the Netherlands, famous for its historical connections with the reigning House of Orange-Nassau, for its blue pottery, for being home to the painter Jan Vermeer, and for hosting Delft University of Technology (TU Delft). Historically, Delft played a highly influential role in the Dutch Golden Age. In terms of science and technology, thanks to the pioneering contributions of Antonie van Leeuwenhoek and Martinus Beijerinck, Delft can be considered to be the birthplace of microbiology.

Dordrecht (Dutch: [ˈdɔrdrɛxt] ), historically known in English as Dordt (still colloquially used in Dutch, pronounced [dɔrt] ) or Dort, is a city and municipality in the Western Netherlands, located in the province of South Holland. It is the province's fifth-largest city after Rotterdam, The Hague, Leiden, and Zoetermeer, with a population of 123,000 (2025).

The municipality covers the entire Dordrecht Island, also often called Het Eiland van Dordt ("the Island of Dordt"), bordered by the rivers Oude Maas, Beneden Merwede, Nieuwe Merwede, Hollands Diep, and Dordtsche Kil. Dordrecht is the largest and most important city in the Drechtsteden and is also part of the Randstad, the main conurbation in the Netherlands.

Capelle aan den IJssel (Dutch pronunciation: [kaːˈpɛlə ʔaːn dən ˈɛisəl] or [- də ˈʔɛi-]; transl. "Capelle on the IJssel") is a large town and municipality in the western Netherlands, in the province of South Holland. The municipality had a population of 67,319 in 2021, and covers an area of 15.40 km (5.95 sq mi), of which 1.26 km (0.49 sq mi) is water. It is situated on the eastern edge of Rotterdam, on the Hollandse IJssel river.

The town has what is probably the country's smallest museum, the Dief- en Duifhuisje ("House of Thieves and Pigeons"). Now a historical museum, it served as the prison for the castle of Capelle and is all that now remains of the 17th-century castle.

Gouda (Dutch pronunciation: [ˈɣʌudaː] ) is a city and municipality in the west of the Netherlands, between Rotterdam and Utrecht, in the province of South Holland. Gouda has a population of 75,000 and is famous for its Gouda cheese, stroopwafels, many grachten, smoking pipes, and its 15th-century city hall. Its array of historic churches and other buildings makes it a very popular day-trip destination.

In the Middle Ages the Van der Goude [nl] family founded a settlement at the location of the current city and built a fortified castle alongside the banks of the Gouwe River, from which the family and the city took their names. Locals long called the settlement Ter Goude, or Tergou or Tergouw [nl] for short.The area, originally marshland, developed over the course of two centuries. By 1225, a canal was linked to the Gouwe and its estuary became a harbour. In 1272 Floris V, Count of Holland granted the city city rights.

Schiedam (Dutch pronunciation: [sxiˈdɑm] ) is a large town and municipality in the west of the Netherlands. It is located in the Rotterdam–The Hague metropolitan area, west of the city Rotterdam, east of the town Vlaardingen and south of the city Delft. In the south, Schiedam is also connected to the village of Pernis via the Benelux tunnel.

The town is known for its historical center with canals, and for having the tallest windmills in the world.

Zoetermeer (Dutch pronunciation: [ˌzutərˈmeːr] ) is a city in the Western Netherlands, in the province of South Holland. The municipality covers an area of 37.05 km (14.31 sq mi) of which 2.60 km (1.00 sq mi) is water. A small village until the late 1960s, it had 6,392 inhabitants in 1950. By 2023 this had grown to 126,998, making it the fourth largest population centre in the province of South Holland, after Rotterdam, The Hague and Leiden. While now a city in its own right, Zoetermeer started out as a suburb of The Hague and is still a part of the Greater The Hague urban area.

The name Zoetermeer (Dutch for "freshwater lake") refers to the former lake north of the town (reclaimed in 1614). Because the name literally translates as "sweet lake" local residents have dubbed Zoetermeer "Sweet Lake City".

The Tower of Babel was the subject of two surviving paintings and one lost painting by Dutch and Flemish Renaissance painter Pieter Bruegel the Elder. The earliest of the three, a miniature painted on ivory, was completed in 1552–1553 while Bruegel was in Rome, and is now lost. The two surviving works are oil paintings on wood panels, sometimes distinguished by the prefix "Great" and "Little" and by their present location: Kunsthistorisches Museum Wien in Vienna and the latter in the Museum Boijmans Van Beuningen in Rotterdam. The Tower of Babel in Vienna is dated 1563, while the version in Rotterdam is undated but widely believed to have been painted sometime after.

The paintings depict the construction of the Tower of Babel, which, according to the Book of Genesis in the Bible, was built by a unified, monolingual humanity as a mark of their achievement and to prevent their dispersion: "Then they said, 'Come, let us build ourselves a city, and a tower with its top in the heavens, and let us make a name for ourselves; otherwise we shall be scattered abroad upon the face of the whole earth.'" God punishes the builders for their vanity by "confusing their speech" into different languages so that they could no longer communicate; however, in both paintings, Bruegel focuses on the construction of the tower rather than the biblical story as a whole.

A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Edsger Wybe Dijkstra (/ˈdaɪkstrə/ DYKE-strə; Dutch: [ˈɛtsxər ˈʋibə ˈdɛikstraː] ; 11 May 1930 – 6 August 2002) was a Dutch computer scientist, programmer, mathematician, and science essayist.

Born in Rotterdam in the Netherlands, Dijkstra studied mathematics and physics and then theoretical physics at the University of Leiden. Adriaan van Wijngaarden offered him a job as the first computer programmer in the Netherlands at the Mathematical Centre in Amsterdam, where he worked from 1952 until 1962. He formulated and solved the shortest path problem in 1956, and in 1960 developed the first compiler for the programming language ALGOL 60 in conjunction with colleague Jaap A. Zonneveld. In 1962 he moved to Eindhoven, and later to Nuenen, where he became a professor in the Mathematics Department at the Technische Hogeschool Eindhoven. In the late 1960s he built the THE multiprogramming system, which influenced the designs of subsequent systems through its use of software-based paged virtual memory. Dijkstra joined Burroughs Corporation as its sole research fellow in August 1973. The Burroughs years saw him at his most prolific in output of research articles. He wrote nearly 500 documents in the "EWD" series, most of them technical reports, for private circulation within a select group.

Islam is the second largest religion in the Netherlands, after Christianity, and is practised by 6% of the population according to 2023. estimates. The majority of Muslims in the Netherlands belong to the Sunni denomination. Many reside in the country's four major cities: Amsterdam, Rotterdam, The Hague and Utrecht.

The early history of Islam in the Netherlands can be traced back to the 16th century, when a small number of Ottoman merchants began settling in the nation's port cities. As a result, improvised mosques were first built in Amsterdam in the early 17th century. In the ensuing centuries, the Netherlands experienced sporadic Muslim immigration from the Dutch East Indies, during their long history as part of the Dutch overseas possessions. From the dissolution of the Ottoman Empire after the First World War until the independence of Indonesia, the Dutch East Indies contained the world's second largest Muslim population, after British India. However, the number of Muslims in the European territory of the Kingdom of the Netherlands was very low, accounting for less than 0.1% of the population.

The German invasion of the Netherlands (Dutch: Duitse aanval op Nederland), otherwise known as the Battle of the Netherlands (Dutch: Slag om Nederland), was a military campaign, part of Case Yellow (German: Fall Gelb), the Nazi German invasion of the Low Countries (Belgium, Luxembourg, and the Netherlands) and France during World War II. The battle lasted from 10 May 1940 until the surrender of the main Dutch forces on 14 May. Dutch troops in the province of Zealand continued to resist the Wehrmacht until 17 May, when Germany completed its occupation of the whole country.

The invasion of the Netherlands saw some of the earliest mass paratroop drops, to occupy tactical points and assist the advance of ground troops. The German Luftwaffe used paratroopers in the capture of several airfields in the vicinity of Rotterdam and The Hague, helping to quickly overrun the country and immobilise Dutch forces.

Holland is a geographical region and former province on the western coast of the Netherlands. From the 10th to the 16th century, Holland proper was a unified political region within the Holy Roman Empire as a county ruled by the counts of Holland. By the 17th century, the province of Holland had risen to become a maritime and economic power, dominating the other provinces of the newly independent Dutch Republic.

The area of the former County of Holland roughly coincides with the two current Dutch provinces of North Holland and South Holland into which it was divided, and which together include the Netherlands' three largest cities: the capital city (Amsterdam), the home of Europe's largest port (Rotterdam), and the seat of government (The Hague). Holland has a population of 6,583,534 as of November 2019, and a population density of 1203/km.

South Holland (Dutch: Zuid-Holland [ˌzœyt ˈɦɔlɑnt] ) is a province of the Netherlands with a population of over 3.8 million as of January 2023 and a population density of about 1,410/km (3,700/sq mi), making it the country's most populous province and one of the world's most densely populated areas. Situated on the North Sea in the west of the Netherlands, South Holland covers an area of 3,308 km (1,277 sq mi), of which 609 km (235 sq mi) is water. It borders North Holland to the north, Utrecht and Gelderland to the east, and North Brabant and Zeeland to the south. The provincial capital is the Dutch seat of government The Hague, while its largest city is Rotterdam. The Rhine-Meuse-Scheldt delta drains through South Holland into the North Sea. Europe's busiest seaport, the Port of Rotterdam, is located in South Holland.
