Auschwitz III (Monowitz) camp, 1944

In late October 1942, the SS authorities at Auschwitz established a large subcamp that became known as Auschwitz-Monowitz. The SS established this subcamp to house Auschwitz prisoners assigned to forced labor at the I. G. Farben synthetic rubber and fuel plant. From November 1943 to November 1944, Auschwitz-Monowitz was designated as a separate camp and known as Auschwitz III. In November 1944, it became a separate concentration camp known as Monowitz. Prisoners sometimes called the camp “Buna.” Buna was the brand name for the synthetic rubber produced at the I. G. Farben factory.
