Werksgasthaus Gutehoffnungshütte, building in Oberhausen, Germany

The Werksgasthaus der Gutehoffnungshütte is a 1913 building by architect Carl Weigle on Essener Straße in Oberhausen, set in a park and conceived with neoclassical elements as a near-counterpart to nearby Schloss Oberhausen. Inside are meeting rooms and a large hall with a stage; the basement held a wine cellar with tasting corner and a bowling alley. It now forms TZU I of the Technologiezentrum Umweltschutz, with about 2,800 m² of offices and a 1,200 m² conference centre.

Built in 1913 by architect Carl Weigle for the steel company, the building served as a dining and event space for employees and guests. Damaged during the Second World War, it was repaired and designated as a heritage monument in 1987, later renovated as a technology center.

The building served as a gathering place where workers and managers of the steel company came together for meals and celebrations. Its role as a social hub remains visible in the large hall and event spaces that hosted community occasions.

The former Werksgasthaus is now TZU I of the Technologiezentrum Umweltschutz, with around 2,800 m² of offices and a 1,200 m² conference centre, so the building is generally entered for events rather than as a museum. The complex lies on Essener Straße, and the Werksgasthaus is a stop on the Route der Industriekultur. The neighbouring TZU II is the curved two-storey building behind it; the Fraunhofer Institute (TZU III) stands about 2 km further east.

The basement originally contained a wine cellar with a tasting area and a small bowling alley, revealing the luxurious facilities provided for employees. These features show the high standard of comfort and recreation that the company offered within its industrial complex.
