The Berlin Wall (German: Berliner Mauer) was a wall that separated the city of Berlin in Germany from 1961 to 1989. It separated the eastern half from the western half. Many people believed it was a symbol of the Cold War. The Berlin Wall was taken down on November 9, 1989. The Berlin Wall was about 168 kilometres (104 miles) long. It was built to prevent people from escaping from the eastern half of Berlin.
