The events of the past have left their mark on the cityscape - and the city is still changing today. "Berlin is always in the process of becoming", remarked historian Karl Scheffler, and this is one of the traits that makes it one of Europe's most vibrant, exciting and colourful capitals. Berlin has a vibe all of its own, and wherever you go, you can experience the pulsating life on the boulevards, in the art galleries and at the flea markets, and in the city's 300 clubs and 7,000 bars and restaurants - many of which are open around the clock.
