The complex bedrock structure at the Manfredi Castle (Supersano, Lecce)

Reflection seismic, GPR and penetrometer surveys, were performed at the Manfredi Castle (Supersano, Lecce, Italy) in order to help the engineers in the restoration work. The study tries to understand: 1) whether, using high-resolution reflection seismic data, is possible to provide an essentially continuous structural image of the shallow subsurface; 2) to reconstruct, using both seismic and penetrometer surveys, the bedrock surface below the castle; 3) to discover, using GPR data, the presence of features of archaeological interest. From a technical perspective, the survey was successful. The reflection seismic data effectively image the shallow subsurface and support the penetrometer data. The GPR data pointed out the presence of some man-made structures that could be of archaeological interest.
