This is Marble Arch
Marble Arch is a white Carrara-marble monument at the junction of Oxford Street, Park Lane, and Edgware Road, almost directly opposite Speakers’ Corner in Hyde Park in London, England. The arch is on a large traffic island, which also includes a very small park, in the midst of swirling traffic. The traffic island is directly across from the Marble Arch tube station.
The name “Marble Arch” also refers to the locality in west London where the arch is situated, particularly, the southern portion of Edgware Road. Historically, only members of the royal family and the King’s Troop, Royal Horse Artillery, have been allowed to pass through the arch in ceremonial procession.
