Apsley House, also known as Number One, London, was the London residence of the Dukes of Wellington and stands alone at Hyde Park Corner. The house is now looked after by English Heritage and is open to the public as a museum and art gallery. It is sometimes referred to as the Wellington Museum and It is perhaps the only preserved example of an English aristocratic town house from its period. The rooms have been maintained as far as possible in the original style and decor. It contains the 1st Duke's collection of paintings, porcelain, the silver centrepiece made for the Duke in Portugal, c 1815, sculpture and furniture.
