The Jaworzno concentration camp was a concentration camp in WW2 German-occupied Poland and later in Communist Poland. It was first established by the Nazis in 1943 during the Second World War and was later used from 1945 to 1956 by the Soviet NKVD and then by the Ministry of Public Security and other agencies of the Polish communist regime. Today the site is an apartment complex and also houses a memorial to the camp's victims. Originally, it was established as a Nazi concentration camp called SS-Lager Dachsgrube ("SS Camp Dachsgrube) also known as Arbeitslager Neu-Dachs ("Work Camp Neu-Dachs") established during World War II by the Third Reich on the territory of German-occupied Poland in Jaworzno, Lesser Poland. The camp operated under the Nazi German administration from June 1943 until its evacuation in January 1945. After the communist takeover of Poland, the camp was reinstated and run first by the Soviet Union and then the People's Republic of Poland till 1956, mainly to intern the local German population, who had formed the region's majority population. During this period, it was renamed as the Central Labour Camp in Jaworzno (Centralny Obóz Pracy w Jaworznie, COP Jaworzno). During the German occupation of Poland The Nazi concentration camp at Jaworzno was opened on June 15, 1943, as one of many subcamps of the Auschwitz concentration camp. The camp, known as SS-Arbeitslager Neu-Dachs (often also called SS-Lager Dachsgrube), provided forced labor for the German war industry. Inmates were primarily employed in coal mining in Jaworzno, and in the construction of the power plant "Wilhelm" (renamed "Jaworzno I" after the war) for Albert Speer's company EnergieVersorgung Oberschlesien AG (EVO). Among the builders of the camp were British prisoners of war from the Stalag VIII-B at Lamsdorf (Łambinowice). The camp's guard unit of about 200 to 300 SS personnel was composed mostly of the ethnic German Volksdeutsche from occupied Poland and other countries, led by camp commandant Bruno Pfütze and his deputy Paul Weissman. There were up to 5,000 inmates interned in the camp at any time. The prisoners were composed of various nationalities, chiefly European Jews (about 80% of all inmates); by the time the camp begin its operation, the local Jews of Jaworzno (who numbered about 3,000 before the war) and of the rest of Poland had already been mostly exterminated. There were also Poles, Germans, and others, as well as Soviet prisoners of war.
