Prison camp as the last place of residence?

[mally]

Where would you enter a prison camp (or forced labour camp) as the last place of residence/address?

at (bei): Straflager
city: Allendorf?
Not sure here.

I’ve had quite a few of these. I would enter the following: „z. Zt. Straflager Allendorf“ (z. Zt. = zur Zeit i.e. currently) in one of the fields „bei“ or „Stadt“.

best, Peter
