The ADGB Trade Union School (Bundesschule des Allgemeinen Deutschen Gewerkschaftsbundes (ADGB)), is a training centre complex in Bernau bei Berlin, Germany. It was built for the former General German Trade Union Federation, from 1928 to 1930. It is a textbook example of Bauhaus functionalist architecture, both in the finished product and in the analytical and collaborative approach used develop the design and complete the project. Next to the Bauhaus Dessau building, it was the second-largest project ever undertaken by the Bauhaus.
