West Wycombe (Buckinghamshire)
"The lavishly decorated Palladian villa and exquisite, tranquil landscape garden – featuring temples, lake and streams – were created by the infamous 2nd Baronet, Sir Francis Dashwood, founder of the Dilettanti Society and Hellfire Club. It is still home to the Dashwood family today." Owned by the National Trust. http://www.nationaltrust.org.uk/west-wycombe-park-and-village (from which the photo is taken).
