Watching brief by R Humphrey of PCA during the construction of an extension revealed evidence of modern disturbance and no finds or features of archaeological interest.
Evaluation by H Knight of MOLA revealed an alluvial or colluvial layer likely to have been deposited through the later prehistoric period, but no features of archaeological interest. An area of hardstanding partially surrounded by a brick wall foundation is likely to have been built in the 20th century, but probably later than the construction of the adjacent Brooklands racing circuit.
Excavation (1978) by Dr D.G. Bird for SyAS and DOE of a supposed pre-Conquest manor site revealed a possible medieval ditch system and part of a later brick building. Finds of all periods from 13th to 19th century were made. (154; report in SyAC 96)
Excavation (1975) by Nancy Cox for Mayford History Society discovered Mesolithic flints and led to the rediscovery of an earlier collection of over 1500 implements from the site, some of them of the Upper Palaeolithic. Later excavation (1977) by C. Bonsall for Mayford History Society, SyAS, DOE and the British Museum confirmed the importance of the site and collection. (126 and 139)
Traces of a revetment of a possible earlier moat were recorded in a workman's trench (Nov 1975) by Dr A.G. Crocker. A 15th century pottery sherd was associated with the revetment. (125)
Two seasons of excavation (1975 and 1977) by F.H. Thompson for the Society of Antiquaries and SyAS concentrated on the defences and a number of anomalies indicated by gradiometer survey by A.J. Clark. The defences consisted of a single stone-faced rampart and a V-shaped ditch, possibly right round the promontory. The primary ditch silt on the south-east side was sampled for Mr Clark's sediment dating programme.
Excavation (1977) by J.A. Janaway for the Godalming Group of SyAS located 17th and 18th century pits cutting an apparently medieval layer which in one place overlay traces of another deposit containing flint flakes. (141)
Excavation (1976) by J.A. Janaway for the Godalming Group of SyAS revealed 18th /19th century pits and buildings cutting a layer containing medieval pottery and flint flakes. (131)
