Cultural perspectives on the Wall

Dear reader,
yesterday we visited the Ohio University and saw an exhibit about the fall of the Berlin wall. To be honest I didn't learn anything new, which is quite sad, since I would not say that I know that much about it. To me the exhibit was too superficial and did not reach what it's aim was, to really inform about the Berlin wall.
I have never seen such an exhibit before, that's why I can't tell you anything about how this would look like in Germany but still I can say that I expected alot more, due to the fact that the exhibit was from University of Paderborn and I thought they might go much more into depth of this topic.
The international effects of the fall of the Wall were clearly the end of the Cold War, which is the major point to me. Another important fact is the reunion of all Germans, more for themselfes, lesser for the international atmosphere I'd say.
The fact that still some parts of the Wall exist is simply for reasons to remind people of what happened. I don't think that there is more about it than just the wish to show people how the world was only 20 years ago.
The Wall fell in 1989 but still it lives on in many heads. Even today the Ost-West conflict exist. I have never noticed it, until I went to the University of Ilmenau which is in the former DDR. Immediately one was confronted with being a "Wessi" and so on. In most cases people are not serious about what they say, but still some got prejudices which will last for a long time.
