When it was finished in 1830, it was intended as a triumphal entry to central London (Marble Arch, at Hyde Park’s northern corner, was originally Queen Victoria’s triumphal entry to Buckingham Palace). Now it’s the equivalent of a shrug. Minor anecdotes of its relocation and the switch from Wellington’s original statue on top to a smaller statue (Peace Descending upon War, the largest bronze sculpture in Europe) are all this handsome landmark can muster in its little museum, which also discusses the period when the Arch served as a police station. If you buy a joint ticket with the Apsley House, across Piccadilly, you’ll save a couple of pounds; you can take an elevator up with the admission price.
