It was cold in Krakow but Berlin... now that is a cold place. I haven't heard of this camp before, but I bet it was really grim.
They took extreme measures in Aushchwitz when it came to security and to keep he nature of what happened there and free from anyone seeking to destroy it. Was it the same there?
Many visitors try to nick bits of the camp. They get caught and are facing charges. Auschwitz is a memorial and a lot of care is being taken to persist the memory of what a man can do to a man. It's especially important now when people seem to have forgotten and prefer looking away to standing against the evil.
It was surprisingly open. You could just walk in and look around. Very few staff, but they must have someone keeping an eye on things.
