What should German passport holders enter for the 'place of issue' on forms?

Question for German passport holders: what to enter for “place of issue”?

I’m filling out the form that asks for the *“place of issue”* of my passport.

In a German passport, there doesn’t seem to be a clear place listed.

What is the correct thing to enter here?

* the issuing authority (e.g. Bürgeramt XY)?

* simply Germany?

* or an actual city like Berlin / Munich?

What did you put, or what is usually expected?

Thanks in advance!
