Marble Arch

About this work
The Marble Arch is a 19th-century white marble-faced triumphal arch in London, England. The structure was designed by John Nash in 1827 as the state entrance to the cour d'honneur of Buckingham Palace; it stood near the site of what is today the three-bayed, central projection of the palace containing the well-known balcony.
