The Berlin Wall Is Everywhere

A quarter century after its removal, sections of the Berlin Wall dot museums, schools, and public squares from Los Angeles to Cape Town to Seoul: all pleasant resting places for a structure that once separated friends and family from each other during the Cold War, a barrier many risked their lives to cross.

With Sunday marking the 25th anniversary of the Wall's dismantling, there's plenty to say about one of the world's most famous barriers and the city it once divided. But perhaps most interesting now is what has become of the actual concrete that separated West from East Berlin.
