Altes Stadthaus in Dortmund, North Rhine-Westphalia, Germany, is an office block which was built in 1899, and was designed by "master builder"[1] Friedrich Kullrich (a German architect, urban planner and construction officer from Berlin).[2] It was built in the Renaissance Revival architecture (Neo-Renaissance) style. After the office block was severely damaged in World War II, it was rebuilt in a simplified form.
