Trafalgar Park, also known as Trafalgar House, is a 35,871 square feet (3,332.5 m2) country house south of Salisbury, in Wiltshire, England.
The estate was formerly called Standlynch Park, after an ancient settlement of that name recorded in the Domesday book of 1086. The Beauchamp family owned Standlynch Manor during the Tudor period, after which it was bought by the Greene family. They owned it until the 17th century, when it was acquired by the Buckland family.
Standlynch Manor was bought by Sir Peter Vandeput in 1726. Three years later, he had John James design what would eventually become the Trafalgar Park which can be seen today. Sir Peter died in 1748, bequeathing the estate to his son George, who in 1752 sold it to Sir William Young. Henry Dawkins bought it from Young in 1765.
In 1766 Henry Dawkins had John Wood design pavilions to the north and south of the building. He also had Nicholas Revett add a stone portico and remodel the internal architecture of the north wing. The music room was redecorated by Giovanni Battista Cipriani. Dawkins died in 1814, and the estate was presented to the heirs of Horatio Nelson.
During the Battle of Trafalgar off the coast of Spain in 1805, Horatio Nelson was shot and died on 21 October, leaving a widow but no legitimate offspring. Nelson’s closest male relative was his elder brother, the Rev William Nelson, who was given the title Earl Nelson in 1806 along with other titles of Horatio’s. William Nelson pushed for an estate to be made in honour of Nelson's final act of bravery and his great victory. Parliament decided to buy an estate that would become a permanent tribute to Nelson and his family. Standlynch Park was chosen in 1814 by Act of Parliament and was renamed as Trafalgar Park. After William Nelson’s death, his nephew Thomas Bolton changed his name to Nelson and inherited the property. When he died less than a year later, his 12-year-old son Horatio inherited the estate in 1836. Horatio Nelson went to great lengths to ensure that the estate was well maintained; he commissioned a new garden and renovation of Standlynch Church.
