The main camp was located in the German village of Gross-Rosen, now the modern-day Rogoźnica in Lower Silesian Voivodeship, Poland,[1] directly on the rail-line between the towns of Jawor (Jauer) and Strzegom (Striegau).
[4] Due to a change of policy in August 1942, prisoners were likely to survive longer because they were needed as slave workers in German war industries.
Among the companies that benefited from the slave labour of the concentration camp inmates were German electronics manufacturers such as Blaupunkt, Siemens, as well as Krupp, IG Farben, and Daimler-Benz, among others.
During the camp's existence, the Jewish inmate population came mainly from Poland and Hungary; others were from Belgium, France, Netherlands, Greece, Yugoslavia, Slovakia, and Italy.
Following the unsuccessful Polish Warsaw Uprising of 1944, the Germans deported 3,000 Poles from the Dulag 121 camp in Pruszków, where they were initially imprisoned, to Gross-Rosen.
A total of 125,000 inmates of various nationalities passed through the complex during its existence, of whom an estimated 40,000 died on site, on death marches and in evacuation transports.
Female SS staffed the women's subcamps of Brünnlitz, Graeben, Gruenberg, Gruschwitz Neusalz, Hundsfeld, Kratzau II, Oberaltstadt, Reichenbach, and Schlesiersee Schanzenbau.
The spinning mill where the female Jewish prisoners worked had been "Aryanized" in 1939 by a Vienna-based company called Vereinigte Textilwerke K. H. Barthel & Co.
[8] One subcamp of Gross-Rosen was the Brünnlitz labor camp, situated in the Czechoslovakian town of Brněnec, where Jews rescued by Oskar Schindler were interned.
[10] The most far-reaching expansion of the Gross-Rosen system of labour camps took place in 1944 due to accelerated demand for support behind the advancing front.
The biggest sub-camps included AL Fünfteichen in Jelcz-Laskowice, four camps in Wrocław, Dyhernfurth in Brzeg Dolny, Landeshut in Kamienna Góra, and the entire Project Riese along the Owl Mountains.
