Marble Arch

Marble Arch is a white Carrara marble monument near Speakers' Corner in Hyde Park, at the western end of Oxford Street in London, England, near the tube station of the same name. Only members of the royal family and the King's Troop, Royal Horse Artillery are allowed to pass through the arch.

In 1828, John Nash designed the arch based on the triumphal arch of Constantine in Rome. It was originally erected on The Mall as a gateway to the new Buckingham Palace (rebuilt by Nash from the former Buckingham House).

In 1851, the arch was moved to its present location during the building of the east front of the Palace. (A popular story says that the arch was moved because it was too narrow for the Queen's state coach to pass through, but in fact the Gold State Coach passed under it during the Elizabeth II's Coronation in 1953.)

The arch might eventually be moved back to its original, or a different, location
