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.

The Brandenburg Gate is an 18th-century neoclassical monument in Berlin, Germany. One of the best-known landmarks of the country, it was erected on the site of a former city gate that marked the start of the road from Berlin to Brandenburg an der Havel, the former capital of the Margraviate of Brandenburg. The current structure was built from 1788 to 1791 by orders of King Frederick William II of Prussia, based on designs by the royal architect Carl Gotthard Langhans. The bronze sculpture of the quadriga crowning the gate is a work by the sculptor Johann Gottfried Schadow. The Brandenburg Gate is located in the western part of the city centre within Mitte, at the junction of Unter den Linden and Ebertstraße. The gate dominates the Pariser Platz to the east, while to the immediate west it opens onto the Platz des 18. März beyond which the Straße des 17. Juni begins. One block to the north stands the Reichstag building, home to the German parliament , and further to the west is the Tiergarten inner-city park. The gate also forms the monumental entry to Unter den Linden, which leads directly to the former City Palace of the Prussian monarchs , and Berlin Cathedral. Throughout its existence, the Brandenburg Gate was often a site for major historical events. After World War II and during the Cold War, until its fall in 1989, the Berlin Wall obstructed the gateway, and was for almost three decades a marker of the city's division. Since German reunification in 1990, it has been considered not only a symbol of the tumultuous histories of Germany and Europe, but also of European unity and peace.
