Berlin’s most famous and potent symbol is this neoclassical triumphal arch topped by the famous Quadriga, a four-horse copper chariot drawn by the goddess Victoria. Since its completion in 1791 it’s seen many of the major turning points of German history, from the revolutions of 1848 and 1918 to the fall of the Wall in 1989, when hundreds of thousands of East Germans streamed through the gate into West Berlin. Today it’s still the site of city-wide demonstrations, celebrations (from New Year’s Eve fireworks to World Cup match screenings), and many a selfie. There’s not much to see besides the gate itself, but you can step into the interfaith “room of silence” in the right watchtower.
