Würselen lies north of the city of Aachen in the immediate vicinity of the tripoint of Belgium, Germany and the Netherlands. Its neighbouring settlements are, in clockwise order, the towns of Herzogenrath, Alsdorf and Eschweiler and the city of Aachen. Würselen is part of Aachen's Nordkreis quarter and is the only part of the city borough without external boundaries.
Subdivisions
As part of the administrative reform in North Rhine-Westphalia and the related 1971 Aachen Act, the territory of the borough of Würselen was expanded in 1972 to incorporate the hitherto independent municipalities of Bardenberg and Broichweiden. Since then Würselen has consisted of the following quarters:
The coat of arms show the eagle of the coat of arms of Aachen in the topleft corner. The second quarter shows the coat of arms of the Rhine Province, however the bend also represents the river Wurm which flows through the town. The mining tools in the third quarter remember the mining history of the town, which dates back till the 12th century. The cross in the fourth quarter is the symbol of the prince-bishopric of Cologne, as the town belonged to the archdiocese of Cologne until the creation of the diocese of Aachen.
History
During the time of the Roman Empire, Roman soldiers were based at Würselen, on an area today known as "Mauerfeldchen" (small mural field).
The first mention of the town was as Wormsalt in 870. Between 1265-69, Duke Wilhelm IV of Jülich built the castle of Wilhelmstein. Since 1616 the town has been known as Würselen. In 1972, the neighbouring municipalities of Bardenberg and Broichweiden were incorporated into the town.
