I was never aware of it. I just stumbled onto this:

http://www.schloesser.bayern.de/engl...oto_permit.htm

Can anyone share recent experience if they can photography inside or outside of Schloss, residenz, etc.. without a permit?

Reading the Permission and Costs section is quite interesting (or really?)

Did anyone ever applied for a permit? What was the outcome?

Thanks for your info and comments.
