A geophysical survey, comprising detailed magnetometry, was carried out over 38ha on land to the north of Winchester. The results indicate the presence of a number of linear anomalies relating to a formerly recorded field system as well as the continuation of Worthy Down Ditch beyond its scheduled area. A single ring ditch was also evident, close to the western end of Worthy Down Ditch. In the north eastern part of the site a curvilinear enclosure with associated linear and rectilinear ditches and pits and/or areas of burning have been located. There is also evidence for later chalk quarrying, with such activity dating to the medieval period recorded on the Historic Environment Record. Further west there appears to be another rectilinear anomaly forming an enclosure feature. Extensive magnetic debris and disturbance relates to the 20th century military use of the site, while ground make-up is evident along the northern edge.
