Limburg (Netherlands) in the context of "Limburg (Belgium)"

Maastricht (/ˈmɑːstrɪxt/ MAH-strikht, US also /mɑːˈstrɪxt/ mah-STRIKHT, Dutch: [maːˈstrɪxt] ; Limburgish: Mestreech [məˈstʀeːx]) is a city and a municipality in the southeastern Netherlands. It is the capital and largest city of the province of Limburg. Maastricht is located on both sides of the Meuse (Dutch: Maas), at the point where the river is joined by the Jeker. Mount Saint Peter (Sint-Pietersberg) is largely situated within the city's municipal borders. Maastricht is adjacent to the border with Belgium and is part of the Meuse-Rhine Euroregion, an international metropolis with a population of about 3.9 million, which includes the nearby German and Belgian cities of Aachen, Liège, and Hasselt.

Maastricht developed from a Roman settlement (Trajectum ad Mosam) to a medieval river trade and religious centre. In the 16th century it became a garrison town and in the 19th century an early industrial centre. Today, the city is a thriving cultural and regional hub. It became well known through the Maastricht Treaty and as the birthplace of the euro. Maastricht has 1,677 national heritage buildings (rijksmonumenten), the second highest number in the Netherlands, after Amsterdam. The city is visited by tourists for shopping and recreation, and has a large international student population. The last stage of the Cretaceous period and the Mesozoic era, the Maastrichtian, is named after this city, at the end of which was the Cretaceous–Paleogene extinction event, which resulted in the extinction of the non-avian dinosaurs.

Roermond (Dutch pronunciation: [ruːrˈmɔnt] ; Limburgish: Remunj [ʀəˈmʏɲ] or Remuunj [ʀəˈmyːɲ]) is a city, municipality, and diocese in the Limburg province of the Netherlands. Roermond is a historically important town on the lower Roer on the east bank of the river Meuse. It received town rights in 1231. Roermond's town centre has become a designated conservation area.

Through the centuries, the town has filled the role of commercial centre and a principal town in the duchy of Guelders. Since 1559, it has served as the seat of the Roman Catholic Diocese of Roermond. The skyline of the town is dominated by the towers of its two churches, St. Christopher's Cathedral and Roermond Minster ("Munsterkerk" in Dutch). In addition to the churches, the town centre has many significant buildings and monuments.

Gelderland (/ˈɡɛldərlənd/ GHEL-dər-lənd, Dutch: [ˈɣɛldərlɑnt] ), also known as Guelders (/ˈɡɛldərz/ GHEL-dərz) in English, is a province of the Netherlands, located in the centre-east of the country. With a total area of 5,136 km (1,983 sq mi) of which 176 km (68 sq mi) is water, it is the largest province of the Netherlands by land area, and second by total area. Gelderland shares borders with six other provinces (Flevoland, Limburg, North Brabant, Overijssel, South Holland and Utrecht) and the German state of North Rhine-Westphalia.

The capital is Arnhem (pop. 159,265); however, Nijmegen (pop. 176,731) and Apeldoorn (pop. 162,445) are both larger municipalities. Other major regional centres in Gelderland are Ede, Doetinchem, Zutphen, Harderwijk, Tiel, Wageningen, Zevenaar, and Winterswijk. Gelderland had a population of about 2,134,000 as of January 2023. It contains the Netherlands's largest forest region (the Veluwe), the Rhine and other major rivers, and a significant amount of orchards in the south (Betuwe).

Liège (/liˈɛʒ, liˈeɪʒ/ lee-EZH, lee-AYZH; French: [ljɛʒ] ; Walloon: Lîdje [liːtʃ]; Dutch: Luik [lœyk] ; German: Lüttich [ˈlʏtɪç] ) is the easternmost province of Wallonia, the primarily French-speaking region of Belgium.

Liège Province is the only Belgian province that has borders with three countries. It borders (clockwise from the north) the Dutch province of Limburg, the German states of North Rhine-Westphalia and Rhineland-Palatinate, the Luxembourgish canton of Clervaux, the Belgian Walloon (French-speaking) provinces of Luxembourg, Namur and Walloon Brabant and the Belgian Flemish (Dutch-speaking) provinces of Flemish Brabant and Limburg.

Viersen (German pronunciation: [ˈfiːɐ̯zn̩]) is a Kreis (district) in the west of North Rhine-Westphalia, Germany. Neighboring districts are Cleves, Wesel, district-free Krefeld, Neuss, district-free Mönchengladbach, Heinsberg and the Dutch province of Limburg.

Kleve (Cleves in English use) or Kreis Kleve is a Kreis (local-government district) in the Lower Rhine region of northwestern North Rhine-Westphalia, Germany. Neighbouring districts are Borken, Wesel, and Viersen in Germany, and the Dutch provinces of Limburg and Gelderland.

The Jeker (Dutch pronunciation: [ˈjeːkər] ; French: Geer, French pronunciation: [ʒɛʁ]) is a river in Belgium and in the Netherlands. It is a left-bank tributary to the river Meuse. The source of the Jeker is near the village of Geer, in the Belgian province of Liège. The river is approximately 54 kilometres (34 mi) long, of which about 50 kilometres (31 mi) is in Belgium (provinces of Liège and Limburg) and 4 kilometres (2.5 mi) in the Netherlands (province of Limburg), where it flows into the river Meuse at Maastricht (Netherlands).

Places through which the Jeker passes include Waremme, Tongeren, Kanne, (all three in Belgium) and Maastricht.

The Maastrichtian ( /mɑːˈstrɪktiən/ mahss-TRIK-tee-ən) is, in the International Commission on Stratigraphy (ICS) geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from 72.2 to 66 million years ago. The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). It is named after the city of Maastricht, the capital and largest city of the Limburg province in the Netherlands.

The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, pterosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about 10 to 15 kilometres (6.2 to 9.3 mi) wide colliding with Earth, ending the Cretaceous.

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally 2⁄3 copper and 1⁄3 zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.

Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small amounts of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been inconsistent, and increasingly museums use the more general term "copper alloy".
