The SS-Baubrigaden were a type of subcamp of Nazi concentration camps that were first established in Autumn 1942. These units were usually made up of male non-Jewish prisoners—most were Poles or Soviets. Chances of survival were higher in these mobile units than the main camps they were attached to. The deployment of the Baubrigaden to major cities within the German Reich was the first time the German public became aware of the living conditions in concentration camps.
