Denbies [SEP] Introduction
Denbies is a large estate to the northwest of Dorking in Surrey, England. A farmhouse and surrounding land originally owned by John Denby was purchased in 1734 by Jonathan Tyers, the proprietor of Vauxhall Gardens in London, and converted into a weekend retreat. The house he built appears to have been of little architectural significance, but the Gothic garden he developed in the grounds on the theme of death achieved some notoriety, despite being short-lived. The estate was bought by Lord King of Ockham following Tyers' death in 1767, and the macabre artefacts he had installed, including two stone coffins topped by human skulls, were removed.
