ADGB Trade Union School, Bauhaus architectural site in Bernau bei Berlin, Germany.

The ADGB Trade Union School is a Bauhaus complex built between 1928 and 1930 near Bernau. Its buildings are arranged on a sloping, wooded site: a two-storey entrance building with foyer, auditorium, dining room, kitchen and administration; a long glazed corridor linking five three-storey residential blocks; and a two-storey building with gymnasium and seminar rooms. The walls are load-bearing masonry with yellow brick cladding, and large windows open onto the landscape.

The General German Trade Union Federation commissioned the school, built from 1928 to 1930 to designs by Hannes Meyer and Hans Wittwer with Bauhaus students. It opened on 4 May 1930 for courses in labour law, industrial hygiene, management and economics. On 2 May 1933 the Nazis confiscated it for a Reich Leadership School training SS, SD and Gestapo leaders.

The school's name comes from the General German Trade Union Federation (ADGB), which commissioned it to train union administrators and leaders in labour law, industrial hygiene, management and economics. Hannes Meyer grouped the 120 trainees into circles of ten who studied, ate and lodged together for four-week courses, following Johann Heinrich Pestalozzi's principle of dissolving a large community into small circles. The four residential blocks carry blue, green, yellow and red schemes, lightening floor by floor, so short-course trainees could orient themselves and be grouped into teams for sports.

The site lies on a sloping, wooded plot north of Bernau; the glazed corridor linking the five residential blocks drops about five metres along its length, so expect a steady descent and climb. The entrance building was altered in 1952–53 and again in the 2003–2007 restoration, which kept those later additions. Check opening arrangements before travelling, as the complex is used as a school.

Each residential wing deliberately houses only ten students per group to create tight-knit communities and stronger personal connections. This design choice directly reflects the educational philosophy that shaped the school's original founding and mission.
