Where were these castle pictures from WW II taken?

I have four pictures taken during WWII but one of them isn't so great, although it does seem to show a tall tower within the building somewhere (added this pic--view from hill in back of castle). My Dad took these pics somewhere in Europe, perhaps France, Czechslovakia, Belgium or Germany. He's nearly 93 and can't remember where it was. A name and location would be nice. It looks kind of cool, but the pictures are so close up that it's hard to tell the overall look of the place. Perhaps that oddly-roofed turret tower may help.
