Claremont Landscape Garden [SEP] Stewardship
Also within the grounds is the Belvedere Tower, designed by Sir John Vanbrugh for the Duke of Newcastle. The tower is unusual in that what appear to be windows, are actually bricks painted black and white. It is now owned by Claremont Fan Court School, which is situated alongside the gardens. In 1949 the landscape garden was donated to the National Trust for stewardship and protection. Initially it was managed by Esher Urban District Council who could do little more than basic maintenance and grass-cutting. in 1974 the National Trust took back control of the site and a pioneering restoration programme was launched in 1975 following a significant donation by the Slater Foundation.
