In 2016 London Stone Conservation was instructed by the City of London Corporation to carry out a cleaning and preventative works program to eight fountains and monuments, located throughout Hampstead Heath.

The Heath, and its various additions and extensions, occupies an area of 790 acres in northwest London. It is a nature conservation area that contains vast open spaces, countless ponds and new and ancient woodland. Set within this wild and leafy landscape are numerous monuments, memorials and marker stones, of significant historical and cultural importance.

The City of London Corporation is responsible for the conservation and maintenance of all public statuary within the City and several other areas in their care, such as many of London’s green spaces. The project included the clearing, consolidation and cleaning of various markers and milestones; the conservation steam cleaning of a figurative sculpture; the cleaning and overhaul of a granite and bronze drinking fountain; the repair of a marble memorial fountain; the treatment of iron staining to a sandstone fountainhead; and the renewal of limewash to a limestone obelisk. The works were carried out throughout the Heath, from Parliament Hill, to Golders Hill Park and Highgate Wood.
