You will want to walk over from the Reichstag to the park where the Russian War Memorial is. A nice short walk and an impressive monument, with a T-34 Tank and an Artillery piece up on pedestals. Also, I would want to walk under the Brandenburg Gate, right in the same area, and on down the Unter Den Linden Strasse a few blocks, to a Memorial building on the left side of the street, with columns in front of it, that was a NAZI Memorial before 1946 and now is also a Russian memorial. It is nice to walk the same steps that so many famous (and infamous) people did. I visited it but could not walk under the Brandenburg Gate. There was a little thing called the Berlin Wall in the way. We went through Checkpoint Charlie, a “must see” in my view if it is still there. The second memorial I spoke of is in what was then East Berlin.
I never saw Tempelhof Airport. We flew in from Paris into the French military airport (Air France also flew into there). I forget the name of it, shamefully. It was a much smaller airport, and I remember we walked from the plane right through the German Zollamt (Customs) out into the parking lot in about ten minutes.
There is plenty to see in Berlin. You might want to visit the Olympische Stadion (Olympic Stadium) in Berlin as well. YOu can stand where all the top officials of the Reich reviewed the contestants, and also see the track, and perhaps walk on it, I’m not sure, where Jessie Owens proved the “Supermen” were not so super after all.
Berlin is a great and important city, and even so many years ago, I found the people to be friendly and helpful. I have fond memories of our visit there, and wish I could go back now.
Wish I had known about DWM. Of course, it might not have been restored yet. Much wasn’t, especially on the East side of the Berlin Wall, when I visited Berlin.
