it to the urban district council in 1964 stipulating that that would be the sole use. The council obliged and the Winston Churchill Hall was built in 1965. A smaller barn built in the 16th century, the Little Barn, was converted to a library and opened on 2 November 1937. The original cowbyre was destroyed by fire in 1979 and was rebuilt as an exhibition centre. An archaeological excavation was carried out by the Museum of London Archaeological Service in 1997 around the Farm House. This discovered the remains of the old priory were beneath the house, as this had been the bailey, surrounded by the motte. Restoration The site was refurbished with funding from the Heritage Lottery Fund in April 2007 with the work completed in June the following year. This included the renovation of the Grade II listed Manor Farm library as part of a borough-wide programme by the London Borough of Hillingdon. The Duck Pond Market began in the Great Barn in December 2008, following the refurbishment, and runs twice a month. Winston Churchill Theatre, not included in the original restoration work, received a £370,000 grant from Hillingdon Council in March 2011 to enable its refurbishment. The other buildings on the site are used as an Exhibition venue (the Cow Byre Gallery), community spaces (The Stables and the Manor Farm Community Hut) and as a small interpretation centre and base of the Hillingdon Music Service (Manor Farm House). Since 6 September 1974, all the buildings on the site are Grade II listed, except for the Great Barn, which is Grade II*. Comparable structures Other moated medieval farm complexes survive in the nearby area at Headstone Manor and (without a surviving moat) at Pinner Park. Traces of a moat survived at Harmondsworth Great Barn until 1968. References Citations Bibliography Bowlt, Eileen. M. (1994) Ruislip Past. London: Historical Publications Bowlt, Eileen. M.
