Applicazione di tecniche introspettive non invasive per lo studio delle architetture religiose medievali romane

Understanding the logics of composition and the executive events of architectural works is essential for an aware management and a precautionary and planned preservation of our important heritage in order to safeguard and transmit its historical and aesthetic values. This contribution shows the opportunities offered by non- invasive diagnostic investigations in the knowledge of Early Christian and Medieval churches in Rome which have been significantly transformed between the 15th and 18th centuries. The Ground Penetrating Radar (GPR) technique has been mostly taken into account, highlighting its possibilities of interaction with sonic and thermographic testing. This ongoing work aims at drawing up a methodological protocol for the application of these diagnostic investigations, also referring to the following processing, interpretation and graphical representation of data, focusing on searching for non-visible elements and structures enclosed within the buildings.
