Admiralty Arch is an office building and a monument located at The Mall, a road which serves as one of the the main access to Buckingham Palace in London.
The building is located directly above The Mall and has a number of arches that allow the passage of vehicles and pedestrians through it.
It was designed in 1910 by Aston Webb and built by John Mowlem Company. Also, the sculptor Thomas Brock designed the sculptures 'Navigation' and 'Gunnery' that are located in front of the Arch. One of its unique features is a small nose that sits between the arches. The origins of that nose are totally unknown, however it is believed that it was designed in honor of Napoleon.
In 2000, the Cabinet Office moved into the building's offices, while maintaining its headquarters in Whitehall. Admiralty Arch is also home to the Prime Minister's Strategy Unit and the Social Exclusion Task Force.
