Historical information
Admiralty Arch is a landmark building in London which incorporates an archway providing road and pedestrian access between The Mall, which extends to the southwest, and Trafalgar Square to the northeast. Admiralty Arch, commissioned by King Edward VII in memory of his mother, Queen Victoria and designed by Aston Webb is now a Grade I listed building. In the past, it served as residence of the First Sea Lord and was used by the Admiralty. Until 2011, the building housed government offices, but in 2012 the government sold a 125-year lease over the building to a property developer (Prime Investors Capital, run by Rafael Serrano) for redevelopment into a luxury hotel, restaurant and apartments.

On the inside wall of the northernmost arch is a small protrusion the size and shape of a human nose. It was placed there by artist Rick Buckley in 1997 as part of a campaign against the "Big Brother" society. The nose is at a height of about seven feet, and sits at waist height for anyone riding through the arch on a horse. Prior to Buckley being unmasked in 2011 by the London Evening Standard, an urban myth grew that the nose is there in honour of the Duke of Wellington, who was known for having a particularly large nose.(wikipedia)
