An eye to the future, an eye to the past, thinking to a full-scale restoration process: physical and chemical ndt analysis in cooperation

The case of the S.S. Annunziata Church (1178) located in Roio Colle (L’Aquila, Italy) is studied herein. The case offered the occasion for researchers coming from two Countries (Greece and Italy) to work both in person and in real-time, by using different techniques. In particular, chemical and physical NDT analysis were employed. Micro-samples were also collected and analyzed in a second time. The study started several years ago by the Las.E.R. Lab., i.e., before that the cleaning process of the façade was conducted; it will end in June 2015, i.e,, after 15 years from the first thermographic campaign, and 8 years from the second one. The second step follows the cleaning process, while the last one follow the consolidation process by injection of mortar due to an earthquake. Qualitative and quantitative results have confirmed the alteration of the internal frescoes during the time.
