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). There were also some traces of Saxo-Norman features. The group dated 1690-1720 is considered to be an exceptionally important discovery for its period. (see report in Post-Medieval Archaeol, 71)
