West Wycombe Park (Palladian Mansion)

From Wikipedia -
“The house, which is a Grade I listed building, was given to the National Trust in 1943 by Sir John Dashwood, 10th Baronet (1896–1966), an action strongly resented by his heir. Dashwood retained ownership of the contents of the house, much of which he sold; after his death, the house was restored at the expense of his son, Sir Francis Dashwood. Today, while the structure is owned by the National Trust, the house is the home of Sir Edward Dashwood and his family. The house is open to the public during the summer months and a venue for civil weddings and corporate entertainment, which help to fund its maintenance and upkeep.”
