Work has begun on the £4.2m restoration of formal gardens at an 18th Century park in Reigate, Surrey.
Archaeologists were called in before the revamp got under way at Priory Park to find out how much of an 18th Century driveway, now underground, remained.
Tree-lined avenues are being renewed and the lake fenced off for dredging, Reigate and Banstead council said.
Contractors appointed have previously completed restorations at Chatham's historic dockyard and Tonbridge Castle.
The restoration of the Historic Dockyard in Chatham won an EU prize in 2005 under the Cultural Heritage awards, Europa Nostra.
The dockyard had completed an £18m programme and was given a medal for restoration which retained "the atmosphere of a working dockyard site successfully blended with new income-generating activities".
Developments planned for Reigate Priory include creating a teenage area with skateboard and basketball facilities and the construction of a glass pavilion to house a cafe, toilets and information facilities.
