Watching brief by W Weller of SCAU showed the site to have been severely disturbed. However, a large ditch of probable Roman date was observed close to the main school building and is possibly a continuation of ditches excavated by S S Frere in 1939 and 1940 (SyAC 48, 45–60). A compacted chalk layer, which may represent a courtyard area between buildings noted on the Ewell Enclosure Map of 1803, was also recorded. A quantity of worked flint of Mesolithic, Neolithic and later Bronze Age date was recovered, indicating activity during these periods within the vicinity.
