English: The Wellington Arch, also known as the Constitution Arch, is a Grade I-listed triumphal arch by Decimus Burton that forms a centrepiece of Hyde Park Corner in central London,

From its construction (1826–1830) the arch stood in a nearby location, slightly to the east, directly across from Burton's Ionic screen entrance to Hyde Park; it was moved a short distance to its current site at the top of the Constitution Hill road in 1882–1883. The triumphal arch originally supported a colossal equestrian statue of the 1st Duke of Wellington by the sculptor Matthew Cotes Wyatt, now to be seen in Aldershot, Hampshire.

"Peace descending on the Quadriga of War" by sculptor Adrian Jones, a bronze of the Goddess of Victory Nike riding a quadriga (an ancient four-horse chariot), has surmounted the arch since 1912, copying the style of the 1791-built Brandenburg Gate in Berlin, which is also surmounted by Victory/Peace with a Quadriga.
