The East Side Gallery between Friedrichshain and Kreuzberg is the longest surviving section of the Berlin wall. It was originally painted back in`90 as a memorial to what freedom should be.
Unfortunately of course freedom means that these things can be tagged over, so that means quite a few of them were restored back in 2000 and then all of them are repainted in 2009.
Probably the most notorious of all the pics along the wall is the kiss, because this is what they did in the `70-ties, sort of the greeting if you will, between a lot of the heads of state in the former eastern bloc, which is why I think part of the, part of the reason behind the caption underneath which is:
my God, help me to survive this deadly love!
