Geophysical investigations for the knowledge of the buried structures in the Basilica Julia at the Roman Forum

Within a research project aimed at the study of the archaeological context of the Basilica Julia in the Roman Forum and the reconstruction of the transformation phases of the building, different techniques of geophysical prospecting were performed. In particular, GPR and ERT surveys were carried out and allowed for the acquisition of interesting data on the foundations of the Basilica Julia, built during the late Republican period and rebuilt at the beginning of the Imperial age, and on the buried remains of the previous Basilica Sempronia, built in the 2nd cent. BC in the same area. Moreover, these investigations allowed for the identification of other Republican structures along the southern side of the Roman Forum and documented the route of the Cloaca Maxima and the palaeosoil.
