The room is 30 meters long. I don't think having the light on in the adjacent room is going to illuminate the chamber via the peephole. Not very much.mengelemyth wrote: ↑Wed Mar 25, 2026 10:57 am Peephole or not, that could be resolved by turning off the light in the adjacent room. Regardless, my comment about it being pitch black (or very dark) concerned the (in)ability of a person to get a full kick on the door, without being constrained or knocked over by another. A modest amount of light penetrating through a peephole does not change that fact. Indeed, a weak light through a small peephole may allow you to locate a door, but it will not light up much within the room... my point stands.
Second, some of the potential gas chamber doors identified in the rubble of crematoria at Auschwitz do not have peepholes. I am not well read on the matter of the doors and which were found where. Perhaps this is detailed somewhere, and I will be happy to read more.
I just don't think much hinges (pun intended) on the the doors. There are too any other lines of evidence. Yes, you can kill people with gas in enclosed spaces.
The doors would be an essential part of the gas chamber design. If you are gassing unrestrained prisoners, the door must be very strong. It must be airtight. It must remain airtight even if people attempt to force the door. It must lock from the outside. The door should open outward. These are all properties we should expect to see in the gas chamber doors.
