Stanwick Park (also known as Stanwick Hall) was a palladian country house at Stanwick St John in Yorkshire. It was re-built by the 1st Duke of Northumberland, a great patron of the arts, c1739-1740, mostly to his own designs. The duke's principal seat was Alnwick Castle thus Stanwick Park was always a secondary residence. The 1st duke furnished the interior of the house with many works of art including paintings by Canaletto. As a secondary seat the house was often allocated to a dowager duchess of Northumberland. During World War I the house served as a military hospital. Following the end of the war it remained empty. In 1918 on the death of 7th Duke of Northumberland his heirs became liable for large death duties as a consequence in 1922 8th Duke of Northumberland sold the estate.
