The Biddenham Loop has been the scene of human activity from the Palaeolithic through to the present-day but the majority of the archaeological evidence spans the Neolithic to the early 4th century AD. Apart from two handaxes, probably brought up from deep within the gravel by recent quarrying, no evidence for Palaeolithic activity was recovered. Given that the Biddenham area once had a reputation as a prolific source of material of this date, its absence is explained by the developments relatively limited impact on the underlying gravel terrace. The report looks at each chronological phase individually, and gives a site narrative, with plans and section drawings as well as detailed structural, artefactual and ecofactual data, primarily by 'activity' type.
