The Brandenburg Gate is a monumental gate built in the eighteenth century as a symbol of peace. During the Cold War, when the gate was located right near the border between East and West Berlin, it became a symbol of a divided city.The Brandenburg Gate is situated at the end of Unter den Linden, a grand boulevard in Berlin. It was one of 18 gates within the Berlin Customs Wall (Akzisemauer) erected in the 1730s, including the old fortified city and many of its then suburbs. The monumental gate was designed by Carl Gotthard and commissioned by emperor Wilhelm II. The design of the gate, 65.5 meters wide and 28 meters tall was based on the Propylaea, the gateway to the Acropolis in Athens. It was constructed between 1778 and 1791 and replaced an older city gate. The decorations, including bas-relief scenes depicting Greek mythology took another four years to complete
