East Side Gallery

You can walk back to Warschauer Strasse or head on back to Ostbahnhof.

Honestly there is a lot to say about the East Side Gallery, but strangely, I personally never made it there myself. However, a few things I can say about it have to do with a controversy regarding tearing down this artistic monument in favor of some luxury apartments. Needless to say, this didn't go over very well. A massive protest was organized, and even The Hoff came out to speak out against this. They managed to delay destroying some of it for a few weeks, but ultimately it's now a shadow of it's former self.

If you're interested in it, you should probably read the wiki instead. It includes some of the artwork itself at the bottom of the article. Berlin is famous for this kind of art, even in places it's not sanctioned.
