Marble Arch is a 19th-century white
marble faced
triumphal arch and London landmark. The structure was designed by
John Nash in 1827 to be 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. In 1851 it was relocated and following the widening of Park Lane in the early 1960s is now sited, isolated and incongruously, on a large traffic island at the junction of
Oxford Street,
Park Lane, and
Edgware Road.
