Why are we drawn to certain cities? Perhaps because of a story read in childhood. Or a chance teenage meeting. Or maybe simply because the place touches us, embodying in its tribes, towers and history an aspect of our understanding of what it means to be human. Paris is about romantic love. Lourdes equates with devotion. New York means energy. London is forever trendy.Berlin is all about volatility.Berlin is a city of fragments and ghosts, a laboratory of ideas, the fount of both the brightest and darkest designs of history's most bloody century. The once arrogant capital of Europe was devastated by Allied bombs, divided by the Wall, then reunited and reborn as one of the creative centers of the world. Today it resonates with the echo of lives lived, dreams realized, and evils executed with shocking intensity. No other city has repeatedly been so powerful and fallen so low; few other cities have been so shaped and defined by individual imaginations.
