The coin issued by the National Bank of Poland is dedicated to the victims of KL Warschau camp. Konzentrationslager Warschau was a German Nazi concentration camp established on the grounds of the former Warsaw Ghetto, functioning from July 1943 to August 1944. Initially it functioned as an independent camp, later it was transformed into a branch of the Majdanek camp. At least 7250 prisoners passed through the camp. They were Jews from various European countries, who were forced to work on dismantling the ruins of the ghetto and on obtaining and segregating all valuable property still located on its territory. The camp and the adjoining ruins were also used by the Germans as a place of execution. Polish political prisoners, victims of round-ups and Jews captured "on the Aryan side" were shot in large numbers there. The number of victims of KL Warschau is estimated at around 20 000. At the end of July 1944 the Germans began to evacuate the camp. Nearly 4 000 prisoners were driven on foot to Kutno and those who survived were taken to KL Dachau. On August 5th, 1944 the camp was captured by soldiers from "Zoska" battalion, who liberated 348 Jews still living there. On the obverse of the coin there are brick barracks with the wall of the concentration camp, immortalized on the insurgent photographs of August 5th, 1944. On the reverse of the coin there is an outline of the barracks with a broken barbed wire and the symbol of Fighting Poland.
