Krupp-Industrietechnik Duisburg office building

The Krupp-Industrietechnik office building was a five-story structure of glass and concrete with spacious open-plan offices on every floor. Its steel-and-concrete frame created a transparent facade that dominated the street corner at Franz-Schubert-Strasse 3.

Construction took place between 1962 and 1963 for Fried Krupp Machine and Steel Construction Rheinhausen GmbH, with an expansion added in 1973. The building reflected the post-war rebuilding of German heavy industry along the Rhine.

Locals called the building the 'Aquarium' or 'Glass Box,' reflecting how modern corporate design became part of everyday speech. The structure symbolized the confidence of German heavy industry during an era of rapid industrial expansion.

The site remains visible from the street even though the building itself is no longer accessible to visitors. The location sits among other industrial landmarks, making it convenient to explore several heritage sites in a single visit to this part of the city.

After closing in 1996, the building sat abandoned for nearly three decades before demolition in 2022 made way for new housing plans. This long period of abandonment transformed it from a working office into an urban monument representing the region's industrial past.
