On Mühlenstraße in Friedrichshain-Kreuzberg, Berlin, an outdoor art exhibit clings to what was the formidable Berlin Mauer (wall). Artists and protestors from all over the world were drawn to the site after the wall was torn down. More than twenty years have passed, yet you can still see the scars it left behind in the landscaping and gaping holes in contrasting architecture. The East Side Gallery is the largest open air gallery in the world and is now a symbol of reunification between East and West Berlin, though the process continues. Nearby is my favourite bridge, the Oberbaumbrücke.
