Only the nose knows
A famous feature of Admiralty Arch is its “nose”. On the inside wall of the northernmost arch there is a small protrusion the size and shape of a human nose. There is little or no public information as to why it is there. The nose is at a height of about seven feet, and sits at waist high for anyone riding through the arch on a horse. Tradition holds that the nose is there in honour of the Duke of Wellington, who was known for having a particularly large nose. Royal soldiers would rub Wellington’s nose for good luck as they rode through the arch.
