Stroud Community Land Trust held a Victorian garden party to mark the completion of the Lake at the Lawns Community Spaces project.
Despite the weather, more than 400 people turned out for the event.
The site is the only remaining feature of a nine-bedroom Victorian country mansion and its grounds. Consisting of more than 300 trees, a stream, a network of footpaths and other historic features, its centrepiece is a small lake, which dates to the 12th century.
Stroud Community Land Trust has transformed what was a derelict patch of land into a valuable green space.
Stroud Community TV filmed at the launch, Coun Andy Read of Stroud CLT talks about the history of the site and outlines the restoration work that ahs been carried out.
