It is a Grade I listed building.It is sometimes referred to as the Wellington Museum. The house is now run by English Heritage and is open to the public as a museum and art gallery, exhibiting a large collection of paintings, including 83 formerly in the Spanish royal collection, given to the first Duke. There are many other artworks and memorabilia of the career of the 1st Duke, who was Prime Minister as well the general commanding the British forces to victory in the Napoleonic Wars. The contents include the 1st Duke's collection of paintings, porcelain, the silver centrepiece made for the Duke in Portugal, c. 1815, sculpture and furniture.The 9th Duke of Wellington retains the use of part of the buildings. 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.
