Enhancing the knowledge of underground sites in the archeological area of Rome: a case study from the Palatine Hill

This paper presents recent non-invasive geophysical mea- surements carried out in the central Cryptoporticus on the Palatine Hill (Archaeological central area of Rome). Results obtained from dierent electrical tomographies, Ground Penetrating Radar and noise measure- ments, are illustrated. The studied underground site is one of the better maintained archeological building in hypogea environments of Roman Age: it is part of the Domus Tiberiana, the rst dynastic palace orig- inally built by Nero Emperor after the re of 64 AD. The paper deals with methodology which integrates geological information, geophysical surveys and new technology in a 3D platform to develop a deepen sub- soil image. It will be demonstrated that the acquired knowledge of the site will support repair eorts and the development of an excavations plan that will not irreversibly alter the studied monument. Moreover, the showed application clearly illustrates the potential of full integra- tion of dierent sources of data for preserving historical buildings and monuments.
