Detailed magnetometry was carried out by Archaeological Surveys Ltd within the sports fields at Warwick School. A Roman building had been recently discovered by Archaeology Warwickshire within the site, and the survey was commissioned in order to determine the archaeological potential of a part of the sports field that had been outlined for upgrading. Further survey was also carried out in the wider area in order to assess the archaeological potential within the rest of the site. The results demonstrate widespread magnetic contamination through use of the sports fields and probably ground consolidation and make-up. Although a number of positive discrete and linear anomalies have been located throughout the site, the majority lack a coherent morphology preventing confident interpretation. Subsequent evaluation revealed a number of cut features including possible enclosure ditches and gullies; however, there was no clear correlation between the evaluation and the geophysical survey results. One L-shaped positive linear anomaly may relate to a possible enclosure ditch that has been partially truncated by later ridge and furrow.
