More information : (Centred TL 145974) 'Lynch Farm': RB Complex of ring ditches, enclosures, pit alignments, tracks and ditches. (1) A large area of arable land. Any former occupation has been destroyed by the plough. Perambulated only in parts. No surface finds made. (2) Two seasons excavations have taken place in three areas of the extensive Lynch Farm complex. TL 142972. A pre-Roman settlement is being destroyed by gravel working. In and beside a large pre-Roman ditch were set two cremation burials in vessels closely resembling those recovered from the Longthorpe kilns. TL 145976. Pits and ditches, although damaged by ploughing yielded evidence for occupation throughout the third and at least the first half of the fourth century. An adjoining cemetery, containing one cremation and at least fifty inhumations, presumably served the farmstead. Many of the burials had been in wood coffins and two were in stone cists. TL 149977. Emergency excavations revealed more third and fourth century agricultural features. These included a timber framed aisled workshop, corn driers, numerous drainage channels and a stone revetted basin 13m by 35m. Metal working furnaces of various types were found within the workshop which itself overlay two early Flavian pits. Further evidence of early military occupation in the form of a series of V-shaped ditches which turned a rounded corner. Industrial connections with the military site at Longthorpe seem quite possible. The footings of a Romano-Celtic temple four metres square and constructed of a single layer of pitched limestone were uncovered. While the SW and NE corners were solidly enough built, the south and east wall lines were carried through in rubble and debris derived from some demolished Roman building. Painted wall plaster, fragments of opus signinum and pieces of tile were the main constituents. The temple was almost certainly of timber construction with the central chamber surrounded by a timber verandah. A substantial regular building of coursed, dressed, stone was located during fieldwalking. (3-7) Lynch Farm Roman site. Two phases of ditches have been traced, forming two sides of a temporary camp. (8) Excavations on the main 'defensive' quadruple linear ditches proved them to exhibit great variation in profile. Lack of dating material from the lower filling prevented any estimate of their period of construction, but judging by pottery in the top filling they appeared to have been filled in deliberately sometime after the mid-2nd century. An entrance has been located, and excavation is proceeding with the hope of tracing timber gateworks. (9) Full report of excavation of farmstead and cemetery, with description of finds and discussion of results. TL 144975 Work on the western limb of the lake area revealed an oval pit 2.0m long, 1.3m wide and 0.7m deep which produced quantities of highly decorated pottery and flints of the Beaker period about 1600 BC. Charcoal, associated with the pottery, is yet to be dated. To the west of this pit an enclosure 29.0m by 18.0m was excavated by sections. The ditches were on average 1.3m wide and 0.8m deep. The enclosure was probably of Iron Age date. Part of an adjacent pit alignment was also examined, but no dating evidence was recovered. (10-11)
