Gross-Rosen was a network of Nazi concentration camps built and operated by Nazi Germany during World War II. The main camp was located in the German village of Gross-Rosen, now the modern-day Rogoźnica in Lower Silesian Voivodeship, Poland, directly on the rail-line between the towns of Jawor (Jauer) and Strzegom (Striegau). Its prisoners were mostly Jews, Poles and Soviet citizens.

From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps, including subcamps on its own territory and in parts of German-occupied Europe.
