Geophysical Survey Report, Kenilworth Castle, Warwickshire

Stratascan were commissioned to undertake a geophysical survey of an area outlined for development including the laying of drainage and electrical services. This survey forms part of an archaeological investigation being undertaken by English Heritage. GPR and gradiometer surveys were carried out west of the proposed visitor centre at Kenilworth Castle. The gradiometer survey identified an area of linear magnetic disturbance in line with a series of bollards. A number of linear anomalies typical of services are present in the radar data within the area of magnetic disturbance, but the gradiometry survey was of limited overall success due to the high number of magnetic objects in and around the survey area. Large amplitude complex and discrete anomalies caused by the pathways are seen throughout the data. Anomalies located beneath the path suggest the presence of possible service routes. Few of the observed radar anomalies can be attributed to areas of archaeological activity with confidence. Two areas of complex response situated in the northeast of the survey area may represent areas of archaeological activity but may also be of modern origin as an inspection cover is thought to exist somewhere within the survey area.
