Hütte, was a separate municipality until 1964. Many other companies, espescially in the mining and steel industry built housing estates for their workers near existing cities, rather than separate company towns. A notable example is Siedlung Eisenheim in Oberhausen from the mid-19th century, once home to 1200 steel smelters of the Gutehoffnungshütte, which is now protected as a historic monument.
