Hengelo (Dutch: [ˈɦɛŋəloː] ; Tweants: Hengel) is a city in the eastern part of the Netherlands, in the Twente region, in the province of Overijssel. It is part of a larger urban area that also includes Enschede, Borne, Almelo and Oldenzaal.
Due to its geomorphology, being situated relatively low in the landscape, Hengelo is a place where streams converge. By consequence, it became a crossroad, inhabited early on in history, which has made it into an infrastructural hub and an industrial centre today. For the 19th century industry, water was needed for bleaching textile, while factories also needed water for their steam engines, and for cooling. Over time, Hengelo became known as metaalstad, for its machine factories and electrical engineering companies. In addition, salt mining developed into an important industry too, which also led to the production of chemical derivatives.
