As a quick summary, the city of Berlin, led by the Berlin Wall Foundation (auf Deutsch: Siftung Berliner Mauer), is planning to rebuild sections of the Wall. Tourists who come to Berlin often come to see the symbol of the Cold War, but are surprised and disappointed when they cannot find the Wall anywhere. People have even complained that the people of Berlin destroyed the Wall too quickly in 1989. Hence, the suggestion has been made to rebuild the Wall.
First of all, in case everybody isn't aware, there are currently sections of the Wall still standing, some of which are original sections of the wall and others that are short parts of rebuilt or moved sections of the Wall. I lived for nearly a year just a ten-minute walk from East Side Gallery, the longest stretch of the original Berlin Wall still standing (1.3 km). There's also the Bernauer Strasse section, which was also rebuilt in the 1990s, and includes a memorial museum. There is a double-cobblestone path throughout the city, marking where the Wall ran, and every so often visitors can read information along this path that tell them everything they need to know about the Berlin Wall and the Cold War itself.
What these tourists don't appear to take into consideration is that there actually are people who live in Berlin. Some of these people even lived in Berlin while the Wall was still up. The Berlin Wall was more than just a symbol of what was happening in the world. It was a fundamental part of their lives. It separated family and friends. It meant Berlin residents couldn't get to work. And people died because of it.
And this is why I think the fact that the city of Berlin is trying to rebuild the Wall for the tourists is a disgraceful idea. I realize that Berlin is a very touristy city, but not everything needs to be turned into a tourist attraction. The city seems to be taking very little consideration of how the residents are feeling or what this might mean to them.
In addition, I think the fact that the Berlin Wall was destroyed so quickly by people in both East- and West-Berlin says a lot more about the city than building it again ever will.
