West Wycombe Park is a country house built between 1740 and 1800 near the village of West Wycombe in Buckinghamshire, England. It was conceived as a pleasure palace for the 18th-century libertine and dilettante Sir Francis Dashwood, 2nd Baronet. The house is a long rectangle with four façades that are columned and pedimented, three theatrically so. The house encapsulates the entire progression of British 18th-century architecture from early idiosyncratic Palladian to the Neoclassical, although anomalies in its design make it architecturally unique. The mansion is set within an 18th-century landscaped park containing many small temples and follies, which act as satellites to the greater temple, the house.
The house, which is a Grade I listed building, was given to the National Trust in 1943 by Sir John Dashwood, 10th Baronet an action strongly resented by his heir. Dashwood retained ownership of the surrounding estate and the contents of the house, most of which he sold; after his death, the house was restored at the expense of his son, the 11th Baronet. Today, while the structure is owned by the National Trust, the house is still the home of the Dashwood family. The house is open to the public during the summer months and is a venue for civil weddings and corporate entertainment, which help to fund its maintenance and upkeep.
