Cliveden House.

A wonderful day at the National Trust property, where Prince Frederick, son of George 2nd, was killed by a tennis/cricket ball thus paving the way for his son to become monarch, who became, George 3rd, the grandson of George 2nd, so the monarchy missed a generation. Also where Profumo and others cavorted with Christine Keeler and Mandy Rice Davies in the 1960s. I love those stories.
