also, when we went there for military trips, you could pay to go into the basement / cellers of the Walker, which we did, nothing too neat, although cool signs in german. But we knew that they used to be used during the war.
Also, one of the houses had tours of their basement that used to belong to Himmler or someone? And of course you could see lots of areas where cellars were buried in, man made caves flooded and off limits (most of this I heard 2nd hand from soldiers from other military bases.) But have heard many stories, and when I went to Berlin for Lifeguard course for my unit, we practiced in an Olympic pool that had been built to train the germans before the Olympics. On the big barracks high above you could see shell hits, and swatikas in the brick work, the two men statues out front were obviously Aryan looking. Very interesting to go there.
Sorry to get off topic. Oh, and many, many of the US and British bases in Germany were old SS, Army and Luftwaffe bases that we took over
