Sobibor
The Sobibor death camp was the smallest death camp in Poland and was located near the Sobibor village, in the eastern part of the Lublin district of Poland. It was 5k away from the Bug River. It was the second death camp to be constructed as part of the Aktion Reinhard, being built along the lines of Belzec. Deportation trains entered the ramp through a gate behind the 'green wall', preventing people from seeing what happened inside the camp. Inside the camp there were three larger buildings - the station, the forester's house, and a two storey post office, along with a sawmill and houses for workers. Victims were almost immediately taken to the gas chambers after arriving by rail. Three new gas chambers were built to speed up the killing process.
