I have been here since 1986 and pretty much know where all of the military posts were located and have even been in 97th General Hospital.
The Chapel is now used for offices and gatherings. You cannot go inside the Consulate at all to look around.
I know where the Officers Club was located over at the Abrams Building and have photos of this from the 1950's, including menus. Is this the same Officers Club or was it a club actually located on the 97th General Hospital Grounds? I can take you to that building and club area. It is now the Goethe University and open to the public.
There used to be a small building at the front of the 97th Gen. Hospital grounds, but I believe they were using this as a daycare, possibly a lunch cafe. I don't think this was an Officers Club. With Gibbs, Drake, Edwards, and Atterberry right around the corner, there were plenty of places to go. This building was torn down a couple of years ago.
The Consulate is very strict about photos, so as a warning, don't go over there and take pictures. They are watching you and will come and make you delete them. Not only with cameras but also with plainclothes guards wandering all around the neighborhood. Yes, I worked there and can vouch for this.
The area where the PX and Commissary were located is now the Polizei Presidium.
Message me. I am sure I can help you with some of this.
