The death camp in Treblinka was the second-largest death camp established by the Germans in the course of the Holocaust. Treblinka death camp operated from July 1942 until November 1943, in which time, in the course of Action “Reinhardt” – the extermination of the Polish Jews – some 800,000 people were put to death in Treblinka. The majority of these were Jews from the Warsaw ghetto and smaller ghettos in the occupied territories of central Poland, though transports of Jews also came to Treblinka from Germany, Austria, Bulgaria, Greece, Yugoslavia, the Czech lands, Slovakia, Belgium and France. Among those murdered in Treblinka was Dr Janusz Korczak and around 200 children from the orphanage he ran. The camp was liquidated following the bloody suppression of an armed uprising among the prisoners employed in processing the transports arriving in Treblinka.
The site of the camp in Treblinka is currently a Site of Memory. The central feature of this complex is a monumental memorial comprising 17,000 stones, symbolising the maximum number of people who could be killed in the gas chambers there in a single day. The Site of Memory also encompasses the area of the former forced labour camp, and features a “Black Road” and a small museum pavilion.
