Wellington Arch, also known as Constitution Arch or the Green Park Arch, is a triumphal arch located to the south of Hyde Park in central London and at the western corner of Green Park, where it is isolated on a traffic island. Built nearby between 1826 and 1830 to a design by Decimus Burton, it was moved to its present position in 1882–1883. It once supported an equestrian statue of the 1st Duke of Wellington; the original intention of having it topped with sculpture of a "quadriga" or ancient four-horse chariot was not realised until 1912.
