GPR prospecting in the chapel of Aragon within the Co-Cathedral of St. John (Valletta, Malta)

In this contribution the results of a Ground Penetrating Radar (GPR) prospecting survey in the chapel of Aragon, within the Co-cathedral of St. John in Valletta, Malta, are presented. These results are part of a wider campaign carried out with the final goal of prospecting the subsurface in order to identify voids and/or graves beneath the tomb slabs composing the complex flooring of the entire Co-Cathedral. In particular, in the chapel of Aragon results were compared with historical documents in order to identify possible burial sites. In addition, a 3D digital model of the Chapel has been obtained through the use of photogrammetric techniques with the ultimate goal of integrating the GPR results within the digital model.
