A city of tolerance under Frederic II, an imperial city under Bismarck, dissolved under the Weimar Republic, extremist during the terror of the Nazis, and punished at the end of the Second World War, Berlin has come out of the rubble at the end of the 20th century with a new strength. Symbol of the Hitlerian regime and of the most uncompromising communism, Berlin has metamorphosed into the capital of a unified Germany. In the past decade, Berlin has become the construction site of a new Reichstag, image of the German democracy, of futuristic buildings and incredible museums like the Pergamon or the Charlotteburg. Mythical sites such as the Alexanderplatz, the Unter den Linder, the arch of Brandeburg, the favourite esplanades of the Berliners, the Kurfurstendamn, breathe a new life and are illuminated once a year for the joyful celebration of the Love Parade. For these festivities, young people from all over the world come to express their passion for the city that has now become a symbol of joy and love.
