The Berlin Wall (German: Berliner Mauer) separated the city of Berlin in Germany from 1961 to 1989. It separated the eastern half from the western half. Many people thought it was a symbol of the Cold War. The Berlin Wall was taken down on November 9, 1989. The Berlin Wall was about 168 km (104 miles) long.
On the night of Nov. 9, 1989, the Berlin Wall came down. East German authorities opened the border between East and West Berlin and the door to the fall of tyranny. The wall went up in the early morning darkness of Aug. 13, 1961, to keep millions of people from fleeing communist East Germany after World War II. It fell as suddenly as it had been built.
