Photographic recording of the interior of the buried walls and foundations of the central tower, and the well shaft within the shell keep, by A Norris and D Graham of SyAS. The structure of the tower no longer survives above ground, with the motte having apparently been raised around the lower storeys of the tower, preserving them for examination. The tower was re-used as a well shaft in the later periods, which has been covered with an unprepossessing concrete slab for some years.

Soil stripping, mapping and sampling by J Warrender of KAP (Kent Archaeological Projects). A single pit containing no dating evidence but characteristic of a modern, probably 20th century, feature was revealed.

This second phase of evaluation, by Les Capon of AOC on behalf of TAB Projects Ltd., revealed two tree pits, probably related to the use of the site as allotments. However, the dominant feature was a wide palaeochannel with remains of pollen that provided evidence for the local flora in the late Devensian / Holocene period.

An archaeological evaluation, and watching brief was undertaken by Nick Carter, Chris Clarke and Jonathan Moller of AOC on behalf of Morgan Sindall Plc, at the site of Cranleigh Village Hospital. The evaluation consisted of three machine excavated trenches with the watching brief monitoring both geotechnical investigations and grubbing of foundations.

An archaeological evaluation, by Ian Hogg of AOC for SCC, consisted of a 2x2m hand dug trench located to the rear of the property. An undated yet presumed post medieval boundary ditch on the same alignment as the current property boundary was recorded; this was overlain by made ground deposits.

Watching brief by D&A Graham of SyAS. The footing trenches for a conservatory were inspected. The trenches were only 40cm deep however, and cut entirely within a dark soil level that had been extensively disturbed by drains associated with the existing building. No material earlier than the 20th century was noted.

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.
