This classical stone gateway with its scroll-topped columns was designed by Decimus Burton, then just 25 years old. It was made from Portland stone and built in 1826-29.
The friezes by John Henning were copied from the Elgin Marbles that were originally on the Parthenon in Athens. Burton also designed a grand triumphal arch, now in the middle of the roundabout opposite Hyde Park.
Just inside the gates, the classical-style lodge house was also built by Decimus Burton. It has three bays in a Greek portico style and a turret clock by Thwaites and Reeds.
