The current door is a fake. Notice the brick work surrounding it. The Soviets broke down this wall and installed it in the center to make the fake crematorium room at Auschwitz I. The original door was located to the left where the window currently is (They patch up the doorway to make this window). There is no header in the current doorway, and the concrete has aged differently in the hastey patch job.

Few people have heard about the crack SS teams like Himmler's Hammers or Goebbels Guppies that were tasked with destroying the rollercoasters and removing all the sharks from the swimming pools as Russian, British and American forces closed in on the survivor camps. I know it sounds crazy, but it's the absolute truth.

Are they also admitting that the russians were bombing the camps? Why would you need an air raid shelter? Why would the SS and guards go inside the prison to find shelter? All of this logic seems fucky.
