Apsley House, also known as Number One, London, is the former London residence of the Dukes of Wellington. It stands alone at Hyde Park Corner, on the south-east corner of Hyde Park, facing south towards the busy traffic interchange and Wellington Arch. It is a grade I listed building.
The house is now run by English Heritage and is open to the public as a museum and art gallery, although the 8th Duke of Wellington still uses part of the building as a part-time residence. It is sometimes referred to as the Wellington Museum. It is perhaps the only preserved example of an English aristocratic town house from its period. The practice has been to maintain the rooms 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. Antonio Canova's heroic marble nude of Napoleon as Mars the Peacemaker made 1802-10, holding a gilded Nike in the palm of his right hand, and standing 3.45 metres to the raised left hand holding a staff. It was set up for a time in the Louvre and was bought by the Government for Wellington in 1816 (Pevsner) and stands in Adam's Stairwell.
