What is "silvermere"

Silvermere is an estate in Surrey, England named after its mere – a shallow lake of about ten acres which has a silvery appearance when seen from the surrounding slopes. It was created in the 19th century for the rich architect, William Atkinson, and subsequently became the home of the Seth Smith family, who had also become wealthy from property development. An ancient British burial mound was found on the land and the ' Silvermere Urn' was found within. During World War II, the mere was used for experiments to develop and test the bouncing bomb. The estate is now a golf course and the final green is on an island in the mere.
