A cart-based magnetometer survey was undertaken on a pasture field dominated by prominent ridge and furrow to the immediate south of London Road, Great Glen, in advance of the proposed development of the site. Anomalies commensurate with ridge and furrow and magnetic disturbance have been detected. In addition, a former field boundary which bisects the survey area has been revealed, as have possible features which may have an archaeological origin. The archaeological potential of the site is considered to be low to moderate.
