The only surviving Berlin city gate and a potent symbol of the city. This is the point where ”Straße des 17. Juni” becomes ”Unter den Linden”. The gate was designed by Carl Gotthard Langhans in 1791 and was intended to resemble the Acropolis in Athens. The Brandenburg Gate now symbolizes reunification, after dividing East and West Berlin for decades. This is the site of Reagan’s Mr. Gorbachev open this gate, Mr. Gorbachev tear down this wall speech.
