18 Best Things to Do in Berlin
"With more than 100 paintings, the East Side Gallery is the world's largest (and longest) open-air art gallery. The 0.8-mile stretch of the Berlin Wall, which runs parallel to the Spree River, once trapped East Germans inside. But when the rest of the Wall came crumbling down in 1989, this stretch remained and became a concrete canvas for international artists, who splashed it with murals between February and June of 1990." - Krystin Arneson, Liz Humphreys
