Treblinka I
Poland
The Treblinka labor camp (officially Der SS- und Polizeiführer im Distrikt Warschau Arbeitslager Treblinka, commonly known as Treblinka I) was a German Nazi labor camp operating from September 1941 to 23 July 1944. It was located in Gmina Kosów Lacki in the Sokołów County, along the Siedlce–Sokołów Podlaski–Małkinia railway line, near the village and railway station of Treblinka, from which it derived its name. The camp primarily detained men and women accused of economic and criminal offenses, as well as victims of łapankas and raids. Initially, Polish inmates from the Warsaw District predominated, but over time, the number of Jewish prisoners increased. Inmates mainly worked in a gravel pit adjacent to the camp. Overall, approximately 20,000 people passed through the camp, of whom about 10,000 died or were murdered.
