Wellington Arch, also known as Constitution Arch or (originally) 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 (although it is now isolated on a traffic island). Built nearby between 1826-1830 to a design by Decimus Burton, it was moved to its present position in 1882-83. 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.
