Potsdamer Platz has been a historically significant square in Berlin, Germany, since it emerged as a trading post in 1685. In 1823, it was adorned by the Potsdam Gate, in 1838 it became a major railroad terminal, and by the 1920s it became the city’s heart similar to Times Square. But by 1933, it was the government center for Hitler’s Nazi Party so was reduced to rubble during WWII. When the Berlin Wall was erected in 1961, it became the “dead zone” between East and West Germany. However, after 1990, it witnessed a major rebuilding boom that now attracts 70,000 visitors a day. Surrounding the area is street art, like this red lips sculpture that was wet from a recent rain.
