Looks to be taken in the 1920s.
Very distinctive castle - I'm sure someone will be able to identify it.

Regarding the uniform, if no one here can ID it, you could always post it on the Armed Forces board (but see how you get on here first).
I am wondering about the uniform, it looks foreign to me.
Maybe because of the cap?

Someone might be able to weave some magic and lighten it a bit so we can see the uniform a little more clearly.
