Kortrijk (in English also Courtrai or Courtray; official name in Dutch: Kortrijk, pronounced ; Latin: Cortoriacum) is a Belgian city and municipality in the Flemish province of West Flanders. It is the capital and largest city of the judicial and administrative arrondissement of Kortrijk. The wider municipality comprises the city of Kortrijk proper and the villages of Aalbeke, Bellegem, Bissegem, Heule, Kooigem, Marke, and Rollegem. Kortrijk is also part of the cross-border Lille-Kortrijk-Tournai metropolitan area. The city is on the river Leie, 42 km (26 mi) southwest of Ghent and 25 km (16 mi) northeast of Lille. Mouscron in Wallonia is just south of Kortrijk. Kortrijk originated from a Gallo-Roman town, Cortoriacum, at a crossroads near the Leie river and two Roman roads. In the Middle Ages, Kortrijk grew significantly thanks to the flax and wool industry with France and England and became one of the biggest and richest cities in Flanders. The city is often referred to as City of Groeninge or City of the Golden Spurs, referring to the Battle of Courtrai or the Battle of the Golden Spurs which took place on 11 July 1302 on the Fields of Groeninge in Kortrijk. In 1820, the Treaty of Kortrijk was signed, which laid out the current borders between France and Belgium. Throughout the 19th and 20th century, the flax industry flourished and remains important within the Belgian textile industry today. Kortrijk is the largest city in southern West Flanders, with several hospitals, colleges and a university. Kortrijk was the first city in Belgium with a pedestrian shopping street, the Korte Steenstraat.
