Nieuwe Maas in the context of "Lek River"

Rotterdam (/ˈrɒtərdæm/ ROT-ər-dam, UK also /ˌrɒtərˈdæm/ ROT-ər-DAM; Dutch: [ˌrɔtərˈdɑm] ; lit. 'The Dam on the River Rotte') 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.

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.

Vlaardingen (Dutch pronunciation: [ˈvlaːrdɪŋə(n)] ) is a large town and municipality in South Holland in the Netherlands. It is located on the north bank of the Nieuwe Maas river at the confluence with the Oude Maas. The municipality administers an area of 26.69 km (10.31 sq mi), of which 23.57 km (9.10 sq mi) is land, with 73,924 residents in 2021.

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.

Delfshaven (Dutch pronunciation: [ˌdɛl(ə)fsˈɦaːvə(n)] ) is a borough of Rotterdam, Netherlands, on the right bank of river Nieuwe Maas. It was a separate municipality until 1886.

The town of Delfshaven grew around the port of the city of Delft. Delft itself was not located on a major river, so in 1389 a harbour was created about 12 km (7 mi) due south of the city, to be able to receive seafaring vessels and avoid tolls being levied by the neighbouring and competing city of Rotterdam. This settlement was named "Delfshaven" (lit. 'Port of Delft').

Feijenoord (Dutch pronunciation: [ˈfɛiənoːrt]) is a borough of Rotterdam in the Netherlands, south of the Nieuwe Maas. Feyenoord football club was formed there, but now play in the neighbouring township of IJsselmonde.

It was a centre of shipbuilding in the nineteenth century, principally at the Fijenoord yard.

The Scheur (Dutch pronunciation: [sxøːr] ; Dutch for "The Rip") is a branch of the Rhine-Meuse delta in South Holland, Netherlands, that flows west from the confluence of the Oude Maas and Nieuwe Maas branches past the towns of Rozenburg and Maassluis. It continues as the Nieuwe Waterweg (New Waterway) to the North Sea.

Originally, the Scheur was the northern branch of the river around Rozenburg island and curved south a few kilometres past Maassluis to join the Nieuwe Maas again in the Maasmond ("Mouth of Meuse") estuary near Den Briel. When the Nieuwe Waterweg was completed in 1872, the Scheur was dammed off and connected to the east end of the Nieuwe Waterweg to form the new channelized main mouth of the Rhine-Meuse delta.

The Rotterdam Metro (Dutch: Rotterdamse Metro) is a rapid transit system operated in Rotterdam, Netherlands and surrounding municipalities by RET. The first line, called Noord – Zuidlijn (lit. 'North – South line') opened in 1968 and ran from Centraal Station to Zuidplein, crossing the river Nieuwe Maas in a tunnel. It was the first metro system to open in the Netherlands. At the time it was also one of the shortest metro lines in the world with a length of only 5.9 km (3.7 mi).

In 1982 a second line was opened, the Oost – Westlijn (lit. 'East – West line'), running between Capelsebrug and Coolhaven stations. In the late 1990s, the lines were named after two historic Rotterdam citizens, the Erasmus Line (North – South) after Desiderius Erasmus and the Caland Line (East – West) after Pieter Caland. As of December 2009, these names were dropped again in favour of a combination of letters and colours, to emphasise and clarify the difference between the separate branches, especially of the former East – West line.
