Neston Park is an English country house and estate in the village of Neston, some 2 miles (3 km) south of Corsham, Wiltshire. The name of the village of Neston derives from the name of the house.
The present house dates from 1790 and has been extended several time since then. It is ashlar-built in two storeys (three storey at rear) with a frontage of 8 bays, and is Grade II* listed.
The grounds of the house contain farmland: the estate extends from north of Neston village, southwards beyond Atworth, to South Wraxall, and includes the certified organic home farm with a herd of Jersey cattle and unusual Aberdeen Angus and Jersey cross-bred cattle. The route of the ancient Roman road from London to Bath crosses the home farm from east to west, about 200 metres (700 feet) south of the house. The local portion of the road is sometimes known as the Wansdyke.
The Neston estate was built up by Thomas Tropenell in the 15th century, passed to the Eyre family and then by marriage to the Baronets Hanham. They sold it c.1790 to John Fuller (died 1839), who built Neston House. John was succeeded in turn by John Bird Fuller (died 1872), George Pargiter Fuller, MP (died 1927) and other descendants. The Fuller family became known for their participation in the Fuller, Smith and Turner brewery in London, producer of Fuller's London Pride cask ale.
In 1910, the then Neston Park proprietor John Michael Fuller, MP was created a baronet on the recommendation of the Asquith government. In 1998 James Fuller became the proprietor, estate manager and fourth Baronet.
