Ground penetrating radar survey over a Roman building at Groundwell Ridge, Blunsdon St Andrew, Swindon, UK

A ground penetrating Radar (GPR) survey was conducted over well‐preserved building remains revealed during a previous geophysical survey (1996) covering an apparent complex of Roman activity discovered at Groundwell Ridge to the north of Swindon, UK. Despite unfavourable, clay‐rich soil conditions, the GPR survey provided a detailed plan of the Roman remains to a depth of approximately 1 m, confirming their survival in the very near surface. The GPR results complement the previous earth resistance and magnetic surveys and, together, the data suggest the presence of a high status Roman building, possibly incorporating thermoremanent features, for instance associated with a hypocaust system.
