The fall of the Berlin Wall was important because it represented the end of the Cold War.
Ever since the Berlin Wall was put up in 1961, it was a symbol of the tensions between communism and democracy. It was a symbol of how these tensions divided the entire world. It was the most recognizable physical symbol of this time in history. When the Berlin Wall fell, it was a physical manifestation of the end of the era. It was an action that would have been unimaginable only five years earlier. The fall of the wall was a huge event in the minds of those who were grown up at the time because it represented the end of an era that had never seemed likely to end.
