The following cities have all at one time or another been capitals of Germany: Aachen, Regensburg, Frankfurt-am-Main, Nuremberg, Berlin, Weimar, Bonn (and East Berlin), and, since 1990, Berlin again.
I still have my piece of the Berlin wall from the time I was stationed there.

Was stationed at Templehof from 78 to 80. Missed the place until Merkel left the low-life’s in. I still remember all the fun playing games with our Russian comrades when they “visited” the West. Still have my Russian and East German flag, will sell, very cheap.
