Berlin is the capital and the biggest city of Germany, with a stoic beat that echoes through grand public buildings, glorious museums and theatres, urbane restaurants, bustling pubs and raucous nightclubs. It's a city that thrives on change and that has made a virtue out of reinventing itself.It has a population of about 3.5 million and extends over 889 square kilometers.
Berlin was the capital of Prussia until 1945 and the capital of Germany between 1871 and 1945 and again since the reunification of Germany on October 3, 1990. (The German parliament, called Bundestag, and the German government moved from Bonn to Berlin in 1999.) Between 1949 and 1990, it was divided into East Berlin, the capital of the German Democratic Republic, and West Berlin. It was divided by the Berlin Wall between August 13, 1961, and November 9, 1989.
The city's appearance today is predominantly shaped by the key role it played in Germany's history in the 20th century. Each of the national governments based in Berlin — the 1871 German Empire, the Weimar Republic, Nazi Germany, East Germany, and now the reunified Germany— initiated ambitious construction programs, each with its own distinctive character. Berlin was devastated by bombing raids during World War II and many of the old buildings that escaped the bombs were eradicated in the 1950s and 1960s in both West and East. Much of this destruction was initiated by municipal architecture programs to build new residential or business quarters and main roads. Berlin's unique recent history has left the city with an eclectic array of architecture and sights.
