Hyde Park Corner is between Knightsbridge, Belgravia and Mayfair in London, England. It primarily refers to a major road junction at the southeastern corner of Hyde Park, that was originally planned by architect Decimus Burton. The junction includes a broad green-space roundabout in its centre, which is now the setting for Burton's triumphal Wellington Arch.
Six streets converge at the junction: Park Lane (from the north), Piccadilly (northeast), Constitution Hill (southeast), Grosvenor Place (south), Grosvenor Crescent (southwest) and Knightsbridge (west). Hyde Park Corner tube station served by the Piccadilly line has many accessways around the junction as do its notable monuments. Immediately to the north of the junction is Burton's Ionic Screen gateway entrance to Hyde Park, and Apsley House, the 18th century townhouse of the 1st Duke of Wellington, hero of Waterloo.
