Diamond Jubilee Gardens is a new public garden created on part of the former site of Twickenham Swimming Pool, which opened in 1935 in commemoration of the Jubilee of George V. The public swimming pool closed for repairs in 1981 but did not re-open and the site became derelict. Part of the land opened in 2005 as a public open space. Following public consultation the new riverside garden was created in 2012, renamed in commemoration of the Queen's Diamond Jubilee; a black poplar was planted by HRH Princess Alexandra on 23 June 2012. The design of the garden recalls the former use with swimming lanes demarcated in the grass of the main lawn.
