Last GDR watchtower still standing in Berlin

Everytime I go to Berlin I'm very quickly reminded why this my favorite European city. As soon as I’m getting close to Alexanderplatz, I feel excited to realize that I’m again visiting the German capital. The first time I visited the city was 7 years ago and it’s amazing how the city have changed in that short time: The palace of the republic is gone, the hauptbahnhof is completed and the area around the parliament is getting nicer and nicer. Each time I visit Berlin I get the opportunity to see something new I haven’t seen before and this time it was not an exception: When we were walking near to Postdamer platz we saw a small flyer talking about a watching tower and indeed we found hidden by a tree one of the last remaining surveillance symbols of the GDR.
