Geophysical survey of the Roman and post-Roman site of Proendos, Ribeira Sacra, Lugo, Spain

Abstract

We present a geophysical survey work in the Roman site of Proendos, Sober, Lugo, Spain, which has been carried out on 27,000 square meters of surface area. From a methodological perspective, two different techniques have been compared on the same plot, Ground-penetrating radar (GPR) and magnetometry, showing the pros and cons of each one in granite substrate environments. The results of the chosen method (GPR) have shown a complex and long-term urban reality, part of which can be placed in the Roman period.
