This historical guided tour explores the Sophiensæle from the perspective of the building itself—the former Craftsmen’s Association House—and traces its changing uses and meanings: as a place of education and training for craftsmen (and women), as a site of organization for parts of the labor movement, as a location of forced labor under National Socialism, as workshops for the Maxim Gorki Theater, and finally, from 1996 to the present day, as a venue for the independent performing arts in Berlin-Mitte.
