Headland Archaeology (UK) Ltd undertook a geophysical (magnetometer) survey, covering approximately 26 hectares on land on the western periphery of Banbury, Oxfordshire, to provide information on the archaeological potential of the site of a proposed housing development. The survey has identified an area of clear archaeological potential within the south of the proposed development area including a probable pit alignment and two probable barrows. The anomalies are identified within a particularly variable magnetic background and it is possible that some weaker anomalies of archaeological potential, if present, may remain masked within this background. Elsewhere, localised areas of possible archaeological potential have been identified as possible enclosures, kilns, and isolated ditches. Therefore, on the basis of the geophysical survey, the archaeological potential of the site is generally assessed as being low although a moderate to high potential is ascribed to the south and north-west of the site.
