SNN111120 - Central M40, Land at Overthorpe Road, Banbury, Phase 2 (Northamptonshire section): Geophysical survey

The geophysical survey has yielded a very high number of anomalies certainly or probably of archaeological interest. These appear to comprise large and small mostly curvilinear enclosures grouped across the centre and south-west of the site, perhaps with a second focus to the south-east. A water main running across the site, and the railways to the north (disused) and south (current) of the site boundary caused large areas of magnetic disturbance which could have obscured other anomalies of archaeological origin. Medieval ridge and furrow field system was present across the entirity of the site.
