Tecniche costruttive murarie medievali

Research on medieval masonry techniques in Sardinia (10th–15th centuries) establishes a critical analytical framework connecting quarrying methods, wall stratigraphy, structural performance, and restoration protocols. Based on direct field surveys of roughly 270 monumental sites across the island's four historical giudicati, the investigation classifies fifty stone, brick, and hybrid wall typologies through systematic database modeling and comparative synoptic tables. Quantitative dimensional analysis of ashlar coursing demonstrates a progressive historical refinement in stereotomy, with vertical course height variances decreasing from 40 cm in 11th-century structures to 8–11 cm by the 14th century. Regional technical variations reflect diverse quarry sources, specialized itinerant workshops, and persistent late antique or Byzantine construction traditions, most notably double-leaf load-bearing ashlar masonry with non-structural core infill. The compiled typological criteria enable accurate chronological dating of undated monuments while offering technical conservation guidelines to prevent damage from aggressive modern interventions.
