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)
