Maastricht

Maastricht ( , , ; ) 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 (), 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.
