Heerlen is a city and municipality located in the southeastern part of the Netherlands, within the province of Limburg. It serves as a major urban center in the Parkstad Limburg region, an agglomeration encompassing eight municipalities with a combined population of approximately 250,000 residents. Situated east of Maastricht and north of the German city of Aachen, Heerlen has evolved from a Roman settlement into a significant industrial and cultural hub.

The history of the area dates back to the Michelsberg culture (4400–3500 BC), evidenced by unique archaeological excavations at the Schelsberg. However, the city's formal history began with the Roman military settlement of Coriovallum, established at the intersection of major trade routes connecting Boulogne-sur-Mer to Cologne and Xanten to Trier. The discovery of a Roman bathhouse (thermae) in 1940, now housed within the Thermenmuseum, underscores the site's historical importance.
Following the Roman period, the region saw agricultural development in the Middle Ages. The name 'Herle' first appeared in official documents in 1065. Throughout the centuries, the territory was subject to various authorities, including the dukes of Brabant and the Spanish Netherlands, before eventually becoming part of the Dutch Republic following the 1661 Partage Treaty.
Heerlen remained largely agrarian until the late 19th century. The discovery of coal in 1874 and the subsequent arrival of the railway in 1896 catalyzed a rapid industrial transformation. The national government's decision in 1901 to establish state-operated mines led to a population explosion, growing from 6,646 in 1900 to over 32,000 by 1930. This era of expansion significantly altered the city's architectural landscape.
In the 20th century, the architect Frits Peutz became instrumental in the city's modernization. His most notable work, the Glaspaleis (Glass Palace), remains a landmark of modern architecture and is recognized as one of the most significant buildings of the 20th century. Today, Heerlen balances its industrial heritage with a focus on urban renewal and cultural development within the broader Parkstad Limburg region.
The name first appears as 'Herle' in a document from 1065, referring to an allodium in the bishopric of Liege.
