Highgrove House is the family residence of Charles, Prince of Wales, and Camilla, Duchess of Cornwall, situated south west of Tetbury in Gloucestershire, England. Built in the late 18th century, Highgrove and its estate was owned by various families until it was purchased in 1980 by the Duchy of Cornwall from Maurice Macmillan. Charles remodelled the Georgian house with neo-classical additions in 1987. The duchy manages the estate and the nearby Duchy Home Farm. The house is noted for its extensive gardens which receive more than 30,000 visitors a year. The house and gardens are run according to Charles' environmental principles, and have been the subject of several books and television programmes. Charles frequently hosts various charitable events at the house.
