Berliners come to celebrate their city in this public square, which was completely destroyed during the Second World War and isolated during the Cold War.
Torched by Hitler, bombed by Britain and stormed by the Russians, the seat of German power has risen again as a symbol of a united, progressive Germany.
A city with a rich and often chequered history. Old Berlin has morphed into a contemporary, cosmopolitan city, rich in culture, architecture, museums and festivals.
