Detailed magnetometry was carried out by Archaeological Surveys Ltd over an area of land at Hillworth Road, Devizes, Wiltshire. The survey was carried out in two phases as an additional area to the south was outlined for an attenuation pond at a later date to the initial survey. The results revealed a number of positive linear and rectilinear anomalies in the southern part of the site that appear to relate to cut features with archaeological potential. Elsewhere the site contains a number of linear, curvilinear and discrete anomalies, but they are weak and poorly defined and are of uncertain origin. Other anomalies relate to magnetic debris from ground make-up, and magnetic disturbance from an underground service has also been located in the northern part of the site.
