Excavation by R J Poulton for SyAS, SCAU and Guildford Borough Council in Castle Cliffe Gardens located a large deep ditch which had probably been largely infilled by the early 13th century. It is postulated that it was the original outer bailey ditch, filled in when the Castle was extended further south to the Quarry Street line in the 13th century, for the Royal Palace.
Small-scale excavation by Audrey Monk for Guildford Group of SyAS to test the site which was producing small abraded sherds of RB pottery and tile. A few more abraded RB sherds were found but it is thought doubtful that the excavation evidence supported the hypothesis of a Roman road. (257)
Observation by S P Dyer for SCAU and Golf Drive (UK) Ltd of golf course construction located a few struck flint flakes but no other finds or features of interest.
Investigation by Audrey Monk and Barbara Blatchford for the Guildford Group of SyAS of sections revealed by removal of the swimming pool and trial holes dug by contractors, to check for traces of the medieval manor. Nothing of significance was found but the area had been very disturbed in recent times. (255)
A date was received from the Oxford University Radiocarbon Accelerator Unit for one of the pieces of worked wood found in 1987: 1180±95 BP (OxA-3166), suggesting a mid to late Saxon date. The function of the wood remains so far unexplained. (see report in SyAC 88, 333-336)
Notes by C W Atkins correct mistakes in the published version of Aubrey's Natural history and antiquities of Surrey where it refers to the Parley Heath Romano-Celtic temple. They include details of the rough measurements of the temple and make clear that an odd-sounding reference to Roman tiles is in fact to no more than standard tegulae. (255). An anti-traveller trench dug across part of the temenos area was examined by Judie English and nothing of archaeological interest was noted.
Evaluation by G N Hayman for SCAU and G U Projects, on behalf of the North Surrey Water Co, prior to reservoir enlargement. Two large pit-like features were found, cut by a modern trench so that only one edge of these features was uncovered. Their fill was disturbed chalk and contained a number of Roman sherds of the 2nd century AD. It is thought that the site could represent chalk quarrying activity.
Observation of redevelopment and salvage excavation by J Boas for Guildford Museum recorded a general scatter of post-medieval pottery and two features cut into the natural chalk. The first was a large irregular pit constructed of rough chalk blocks, thought likely to be a cess pit in the stable area of the Three Tuns Inn. It contained a large amount of material dated to 1690-1720, including many more or less complete vessels and a great number of high class goblets. The second feature was a well which contained a large group of medieval pottery provisionally dated 1175-1250. (258).
Work continued on the research/training excavation by R J Poulton for SCAU, SyAS, the Society of Antiquaries and others. The excavation of a section of the bailey ditch was completed. A well-preserved tile kiln was uncovered, its last firing archaeomagnetically dated to AD 1220-1270 at the 95% confidence level. Presumably the tiles produced were used in roofing the earliest palace buildings. (262; 266; see Guildford Castle monograph)
Observation of redevelopment by J Boas for Guildford Museum led to the recording of a Saxo-Norman pit.
