It is completely different compare to other part in Berlin. Many buildings here are new, modern, colorful, erected high...
In some case, there will be such exhibition. And this is a 'hair' exhibition. Cloudy sky above but ok.
This is what Potsdamer Platz looked like when the wall was still there. A huge area with nothing but the wall, the death zone behind and souvenir stalls and tour busses everywhere.
The Potsdamer Platz never fails to elicit oohs and aahs from even the most jaded of city visitors. This is the Deutsche Bahn (German Rail) Tower, for me the most impressive building there.
It is a very significant place in New Berlin. There are plenty of café and bars around a fountain, where you could relax and chill out.
