Walton Hall, Wakefield
I spent last night at Waterton Park Hotel near Wakefield. The hotel incorporates Walton Hall, the traditional home of the Waterton family, which sits on an island in an artificial lake. I thus came across Charles Waterton, the 19th century naturalist and eccentric. He may well have been a friend of Lord Bonkers' grandfather. There is a better photograph (if you ignore the helicopter) of the Hall here.
