Covering Up Their Tracks
Under the command of SS Chief Heinrich Himmler, Sobibor was burnt to the ground and covered with asphalt and cement, basically attempting to expunge it from history. They removed the gas chambers and planted pine trees in order to hopefully cover it all up so that the remains of the death camp would never be recovered. But this was not to be its fate, and the remains of Sobibor were actually rediscovered many years later.
