The ADGB Trade Union School, is a training centre complex in Bernau bei Berlin, Germany. It was built for the former Federation of German Trade Unions, 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.
It was designed by the Bauhaus director Hannes Meyer with Hans Wittwer, who taught the Bauhaus building theory course alongside Meyer. The two architects, both Swiss, had also worked together in their hometown, Basel. Students from the building theory course and other areas of the Bauhaus were also involved with the design, construction and interior fitting of the complex.
In 2017 the ADGB Trade Union School was added to the UNESCO World Heritage Site the Bauhaus and its Sites in Weimar, Dessau and Bernau.
