Genk (ɣɛŋk) is a city and municipality located in the Belgian province of Limburg near Hasselt. The municipality only comprises the town of Genk itself. It is one of the most important industrial towns in Flanders, located on the Albert Canal, between Antwerp and Liège. Genk probably originated as a Celtic village, and was converted to Christianity in the 10th century. The remains of a little wooden church dating from that period were found in the area. The first mention of Genk as Geneche can be found in a document dating from 1108, ceding the territory to the Abbey of Rolduc. Politically, Genk belonged to the County of Loon until it was annexed by the Prince-Bishopric of Liège in 1365. During a century of on-going industrialisation further south in Belgium, Limburg modernised only slowly: Genk remained unimportant and small, growing slowly to a population of 2,000 around 1900. The peaceful village was the home of landscape painters and writers such as Neel Doff. In 1901, André Dumont found a large quantity of coal in the nearby village of As. Soon after, the "Black Gold" was also found in Genk. After World War I, the village started to attract a large quantity of both Belgian and foreign immigrants, and quickly became the biggest town in Limburg after Hasselt, peaking to a population of 70,000. However, in 1966 the coal mine of Zwartberg closed down, and Genk had to develop new industries, mainly along the Albert Canal and highways. By the end of the 1980s, the two remaining coal mines at Winterslag and Waterschei were also closed. In 2000, Genk officially became a city. Genk is the industrial centre of the province of Limburg and offers over 45,000 jobs, making it economically the third most significant city in Flanders. In 1900, Genk was a quiet village with around 2,000 residents. At that time, Genk was known for its natural environment, popular among artists and painters who used Genk as a setting for their pieces. In 1901, coal was discovered in Genk and three mining sites were developed: Zwartberg, Waterschei and Winterslag (C-mine today).
