of an early 16th-century manor house and its surrounding garden. The Second World War ended excavations at Avebury. Keiller joined the special constabulary at Marlborough and as his duties left little time for archaeology, he had the museum mothballed. Legacy In 1943, Keiller sold his holdings in Avebury to the National Trust for £12,000, simply the agricultural value of the he had accrued, and not reflecting the immense investment he had made at the site. His excavations at Avebury were unpublished at his death, but were worked up by archaeologist Isobel Smith and published in 1965. In 1966, his widow Gabrielle Keiller donated the Avebury museum and its contents to the nation. In 1986, UNESCO designated Avebury (together with Stonehenge and associated sites) as a World Heritage Site. In 2000, it received over 350,000 visitors. References Further reading Murray, Lynda J.
