Hoesch Museum Dortmund, Industrial museum in Dortmund, Germany

The Hoesch Museum is located in a former porter's lodge of the Westfalenhütte steelworks and tells the story of iron and steel production in Dortmund. The building holds machinery, tools, and documents that explain the manufacturing process and the region's industrial growth.

The Westfalenhütte steelworks was founded in the 19th century and shaped Dortmund as an industrial city for more than a hundred years. The museum was later established after production ceased, to preserve this heritage.

The museum is run by the Friends of the Hoesch Museum association, whose many volunteers organise the displays; historian Dr. Karl Lauschke chairs it. Its special exhibitions have covered subjects such as Hoesch maritime, migration and religions in the Ruhr, and 150 years of work at the Westfalenhütte, founded on 1 September 1871.

The museum occupies the former porter's lodge at the Westfalenhütte entrance, built 1912–1914 and remodelled in the 1950s; the listed building is a stop on industrial-history routes through Dortmund's north. The steel bungalow stands beside the museum and is used for events and exhibitions. The Förderverein runs the site with volunteer staff, so opening depends on their rota.

Next to the museum stands a steel bungalow that once belonged to a settlement of around 200 such houses built by Hoesch in Hombruch in the 1960s. The 1966 house, made of the composite material Platal, opened in May 2025 and keeps its bathroom and kitchen partly in original condition.
