At its peak activity in 1944, the Gross-Rosen complex had up to 100 subcamps,[2] located in eastern Germany, Czechoslovakia, and occupied Poland. In its final stage, the population of the Gross-Rosen camps accounted for 11% of the total inmates in Nazi concentration camps at that time. 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.
