The Berlin Wall was a physical border set in the city of Berlin which was dividing the communist and democratic part of it. The people were not able to communicate, move between the two sides, or even see each other. The wall was set by the Soviets, and it represented very well how their politics was. When this wall finally was taken down after three decades, it meant that Germany was united again, and that the communism came to an end in the country. The symbolism of the fall of the Berlin Wall though is much wider, and it not only symbolizes the end of communism in Germany, but across most of the world, as it coincided with the period when the Soviet Union was falling apart and numerous countries got independent, free to make their own decisions, and become democratic societies.
