The Nose (in profile) - Admiralty Arch, SW1. Why is it there? Good question. It originated as an ‘art’ installation in 1997, protesting against the nosy ‘Big Brother’ society. But Londoners then imagined a history for it, providing it with a nineteenth century provenance - it was the Duke of Wellington’s nose; it was rubbed by Horseguards for good luck whilst riding through the Arch etc. To find it look above eye level in the eastbound, or north, arch.
