I have tried for a few years now to find a photo of a castle my grandfather was stationed near during WWII with no success. He is getting older and I am running out of options, it would mean the world to him. He was in the 22nd Infantry Regiment of the 4th Infantry Division. He remembers being near this castle but not allowed to visit it. He believes it was in Germany and near a rail line, there was also a creek/stream at the foot of the hill it sat on. I thought it was Altenberg Castle near Bamberg, Germany but he claims this isn't it. Does anyone know the path that this regiment took through the war and what castle(s) it could potentially be?
Well, this is kind of a shot in the dark but...

(sorry I'm not sure how to format links in reddit)
There is a lot more that could be investigated as the 22nd Infantry Regiment assignments seem to be fairly well documented, but I need to go to bed.
Edit: Fixed first link
Another shot in the dark. I went with the Wikipedia entry and combined that with the 4th Infantry Division's list of Command Posts. Your grandfather's regiment was on R&R in Luxembourg for quite a while as per this memoir, so I focused on that area.
Vianden Castle is on a hill, with a stream below, and a railway line. It was also in quite bad repair at the time which might explain why they weren't allowed to visit it.
