Evaluation and subsequent excavation was carried out by J Robertson of SCAU for Nicholas King Homes, before residential development of the school grounds. The site lies outside the Roman and medieval settlement of Staines but in close proximity to the parish church. Numerous features of late Saxon date were revealed, confirming that there had been some shift of settlement during that period away from the site of the Roman town. Some features of Saxo-Norman date were identified, but insufficient to establish whether Duncroft was the site of Staines’ Manor House. A number of features of prehistoric, possibly Bronze Age, date were also recorded. In addition, residual pieces of Roman pottery were recovered. (309, 314)
