The S. Nicolò l'Arena Exedra in Catania was built up in 1722 in front of the homonymous Monastery. The façade is composed by natural and artificial stones: Syracuse stone for portals and windows frames, lava stone for the basement and a reddish plaster for plane surfaces, typical materials of the Catania historic buildings. Its color is due to the introduction of the so-called “ghiara” in the finishing mixture. A multi-technique study is here presented: after the obtainment of a detailed surveying of the building surface through the integration of 3D laser scanner and digital photogrammetry techniques, FTIR-ATR, Raman and XRD analysis were carried out to characterize structures, materials and their alteration products.
