Wellington Arch is also known as Constitution Arch because it stands on Constitution Hill – just off Hyde Park Corner. It was built by Decimus Burton in 1826 to celebrate the Duke of Wellington’s victory in the Napoleonic War.

The black statue on the summit was added in 1914, just before the outbreak of World War I. It is entitled Peace Descending on the Quadriga of War, and is the largest bronze statue in Britain.
Wellington Arch hides three floors detailing the history of the London’s arches – and once housed the second-smallest police-station in the capital. (The smallest being in Trafalgar Square.)
