Northwick Park, Gloucestershire
The estate is built in the grounds of the former family seat of the Rushout family, the Barons Northwick. The Northwick Park mansion, now divided into residential accommodation, is a Grade 1 listed building. It passed out of the Rushout family in 1912, when it was inherited by the then Lady Northwick's grandson, George Spencer-Churchill.
Because the area was under the authority of the Bishops of Worcester, it was actually a small enclave of the county of Worcestershire surrounded by Gloucestershire - and is shown that way on all maps prior to 1931, when such enclaves were rationalised.
The estate includes the site of the former hamlet of Northwick. During the Second World War, Northwick Park was an American field hospital. It became a camp for Polish displaced persons until the 1960s.
Northwick Park collection
The second Baron was an avid collector of works of art, antiques and coins. Much of his collection was housed at Thirlestaine House in Cheltenham and in 1848 he published a catalogue of his holdings there. Although he died intestate and therefore his collection was sold after his death, many items were repurchased by the 3rd Baron. This collection passed to the Spencer-Churchill family. After the death of Captain EG Spencer-Churchill, the collection was sold by Christie's in 1965. Items from this collection can be found in the National Gallery, London and the Metropolitan Museum of Art. The provenance of items from the collection can be investigated using published catalogues of the 1859 sale, the 1864 sale and the 1965 sale. There is also an inventory of the collection produced in 1921 by Tancred Borenius.
