History

During World War II Jasień was the location of the Nazi German slave labour camp AL Gassen, one of nearly one hundred subcamps of the Gross-Rosen concentration camp. Its prisoners, mostly Poles, Soviet prisoners of war, Czechs, Croats and Frenchmen, were making warplane parts for Focke-Wulf AG. The camp, with around 700 acutely malnourished prisoners, operated from August 1944 until 13 February 1945, when the remaining workforce was sent on a death march to the Buchenwald concentration camp ahead of the Soviet advance.
