In the last few years, the improvement of the technologies in the framework of photogrammetric vision and the implementations of new Structure-from-Motion (SfM) algorithms allow to extract metric information's from this kind of images in order to carry out a digital reconstruction of these lost masterpieces. The study presented in this paper aims to evaluate a SfM approach to perform the 3D reconstruction of a dome collapsed in 1971 by using historical images. The final goal is to provide not only a digital replica but also a physical reconstruction of a portion of the collapsed dome as a support for the recovered fragments of the fresco originally present on the surface of the dome.

The chemical composition of the efflorescence is investigated by infrared spectroscopy. The colour palette is determined by means of EDXRF, Raman spectroscopy and visible reflectance spectroscopy. EDXRF has allowed an extensive mapping of the elements present in the pigments and plaster; whilst in-situ Raman spectroscopy has been determinant for attributing the molecular composition of the pigments in a number of doubtful cases. Most pigments identified are typical of Imperial Roman fresco paintings (first to fourth centuries AD) (Ward-Perkins 1981); more interestingly, we found evidence of fragments painted with Egyptian blue, which was normally used mostly in official rooms.

Severely damaged by the earthquake that struck Molise region in 2002, the monument has required complex consolidation works necessitated by serious problems of instability. The paper presents the innovative micro-reinforcement realized as conservation solution to ensure the stability of the stone monument.
