Port of Rotterdam in the context of "Port of Antwerp"

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.

Hamburg, officially the Free and Hanseatic City of Hamburg, is the second-largest city in Germany after Berlin and seventh-largest city in the European Union, with a population of over 1.9 million. The Hamburg Metropolitan Region has a population of over 5.1 million and is the tenth-largest metropolitan region by GDP in the European Union.

At the southern tip of the Jutland Peninsula, Hamburg stands on the branching River Elbe at the head of a 110 km (68 mi) estuary to the North Sea, at the confluence of the Alster and Bille. Hamburg is one of Germany's three city-states alongside Berlin and Bremen, and is surrounded by Schleswig-Holstein to the north and Lower Saxony to the south. The Port of Hamburg is Germany's largest and Europe's third-largest, after Rotterdam and Antwerp. The local dialect is a variant of Low Saxon.

The port of Amsterdam (Dutch: Haven van Amsterdam) is an inland seaport in Amsterdam in North Holland, Netherlands. It is the 14th busiest port in Europe by total cargo tonnage. In 2023, the port of Amsterdam had a cargo throughput of 63 million tons.

The port is located on the bank of a former bay named the IJ and the North Sea Canal, with which it is connected to the North Sea. The port was first used in the 13th century and was one of the main ports of the Dutch East India Company in the 17th century. Today, the port of Amsterdam is the second largest port in the Netherlands, after the Port 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.

The Port of Hamburg (German: Hamburger Hafen, pronounced [ˈhambʊʁɡɐ ˈhaːfn̩] ) is a seaport on the river Elbe in Hamburg, Germany, 110 kilometres (68 mi) from its mouth on the North Sea.

Known as Germany's "Gateway to the World" (Tor zur Welt), it is the country's largest seaport by volume. In terms of TEU throughput, Hamburg is the third-busiest port in Europe (after Rotterdam and Antwerp) and 15th-largest worldwide. In 2014, 9.73 million TEUs (20-foot standard container equivalents) were handled in Hamburg.

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.

The Rhine–Meuse–Scheldt delta is a river delta in the Netherlands formed by the confluence of the Rhine, the Meuse (Dutch: Maas) and the Scheldt rivers. In some cases, the Scheldt delta is considered a separate delta to the Rhine–Meuse delta. The result is a multitude of islands, branches and branch names, in which a waterway that appears to be one continuous stream may have numerous separate names for different sections, e.g. Rhine → Bijlands Kanaal → Pannerdens Kanaal → Nederrijn → Lek → Nieuwe Maas → Het Scheur → Nieuwe Waterweg. Since the Rhine contributes most of the water, the term "Rhine Delta" is commonly used, although this name is also used for the delta where the Alpine Rhine flows into Lake Constance. By some calculations, the Rhine–Meuse–Scheldt delta covers 25,347 km (9,787 sq mi), making it the largest in Europe.

The Rhine–Meuse–Scheldt delta is economically extremely important, since the three rivers are major navigable waterways. The delta is the entrance from the North Sea to the German and Central European hinterland (and to a lesser extent France). Major ports in the delta are Rotterdam, Antwerp (Belgium), Vlissingen, Amsterdam (through the Amsterdam–Rhine Canal), and Ghent (through the Ghent–Terneuzen Canal). The land areas in the delta are protected from flooding by the Dutch Delta Works.
