Abstract: “The paper presents the results of a campaign of non-destructive and minimally invasive tests that were conducted in the church of Santa Maria delle Stelle in Comiso (Ragusa, Sicily), which is the larger church in the Diocese of Ragusa. It includes a summary of the reflections that arose during the preliminary surveys and instrumental tests, and reasons that supported the choice of investigations to be performed and methods to be specifically applied for the consolidation of the architectural structures and plaster layers.”
