It was known as Number One, London because it was the first house encountered from the countryside after passing the tollgates at the top of Knightsbridge.
As well as various Wellington artefacts (no boots, you have to go to Walmer Castle for that), there’s a fantastic art collection, including Velázquez portrait of Pope Innocent I (as found in Joseph Bonaparte’s baggage when he was fleeing after Waterloo).
Interestingly, Napoleon didn’t want the statue when it was finished. One wonders if Wellington was chuffed when he had it presented to him. Apart from anything else, he had to have the hall floor reinforced!
