Apsley House is the London townhouse 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 roundabout in the centre of which stands the Wellington Arch. It is a Grade I listed building.
It is sometimes referred to as the Wellington Museum, its official designation under a 1947 Act of Parliament. The house is now run by English Heritage and is open to the public as a museum and art gallery, exhibiting the Wellington Collection, a large collection of paintings, other artworks and memorabilia of the career of the 1st Duke. The 9th Duke of Wellington retains the use of part of the buildings. It is perhaps the only preserved example of an English aristocratic townhouse from its period. The practice has been to maintain the rooms as far as possible in the original style and decor.
