Detailed magnetometry was carried out by Archaeological Surveys Ltd over 3.5ha at East Hagbourne, Oxfordshire. The survey has located a positive rectilinear anomaly that appears to relate to the western part of a rectilinear enclosure. It contains a number of positive linear and discrete responses that indicate the presence of further cut features within the interior. To the west of the enclosure there are several positive linear, rectilinear, curvilinear and discrete responses, but they are very weak and cannot be confidently interpreted. Very weak linear anomalies associated with ridge and furrow cultivation were also located.
