The geophysical exploration was carried out with a two-fold objective: to obtain a stratigraphic characterisation of the Sector III subsoil, and to test the efficiency and limitations of the geophysical methods applied. These methods are Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT). Our research confirmed the potential existence of buried structures in the subsoil, which shows the potential of the combined used of geophysical techniques in the search for archaeological structures in site's subsoil in a non-destructive manner. The results are shown in different 3D images which allow the characteristics and spatial distribution of the buried structures to be determined, optimising therefore the planning of future archaeological actions.Ground Penetrating RadarElectrical Resistivity Tomographyarchaeological geophysicsAlarcos10.1109/DigitalHeritage.2015.7419474
