One of the lakes concealed an underwater folly which, often referred to as a ballroom, was used as a smoking and billiard room and for observation of the lake fish. A statue of neptune, breaking the surface of the water surmounted the dome beneath.
The folly cost nearly half a million pounds to build but soon after completion, Wright was in trouble. His company collapsed, leaving many investors bankrupt. Wright was charged with fraud and in 1904 was sentenced to seven years imprisonment. He had, however, smuggled a cyanide into court and committed suicide in the presence of his solicitor.
The estate was sold to Lord Pirrie, chairman of Harland and Wolff, builders of the Titanic. Adjacent common land passed the The National Trust. The Leigh family were later owners and changed the name to Witley Park. The house burned down in 1952 and a modern replacement was built on a new site. The follies remain although there is no current access to the underwater passages and rooms.
