Located in Winchmore Hill, London is Grovelands Park which originated as a private estate.
The house was built in 1797 to the designs of John Nash for Walker Gray, a Quaker brewer. The grounds were landscaped by Humphry Repton. The mansion was erected in 1797–1798 and was initially called ‘Southgate Grove’.
After Gray’s death the property was acquired by John Donnithorne Taylor (connected to the Taylor Walker Brewery), whose family continued to live at Grovelands up to World War I.
Part of the estate was purchased by Southgate Council in 1913 to become a public park. The house is part of the Priory Clinic. In 1998, General Pinochet was held under house arrest initially in Grovelands House while a patient at the Priory Clinic.
