Considering the Zum fröhlichen Landmann in Oranienburg?
A VT member wrote the following comment about visiting Oranienburg:
PRISON by Binegars1990
The prison within the concentration camp (1936 -1945) was put up by inmates in 1936, this three-wing block of cells was used as a prison by the Gestapo and the camp authorities. It was a place veiled in secrecy, a place of torment and murder. It held those punished by the SS for infringemnets of camp discipline as well as prominent figures arrested by the Gestapo.
