Architettura e tecnologia delle Terme Nord-occidentali della Villa del Casale a Piazza Armerina: ipotesi ricostruttive di elevati, coperture e impianti idrici

Abstract

The Western Bath complex of the Villa del Casale at Piazza Armerina displays a highly sophisticated architectural and hydraulic layout, reflecting a unified and ambitious design. Examination of the structural evidence, roofing systems, and water-management infrastructure — including the tubulibuilt dome of the octagonal hall, the range of vaulted solutions, and the networks for water supply and drainage — enables a coherent functional reconstruction of the entire bathing sequence. The technical data and estimated water capacities point to facilities comparable in scale and standards to public baths, supporting the view that the complex formed part of an elite residential environment, likely associated with individuals of considerable social standing. A brief architectural reassessment of Room 17a, presented in the Appendix, further refines this picture: the evidence suggests a space decorated with mosaics for private ablutions rather than a service area, and its reinterpretation contributes to a more nuanced understanding of domestic comfort and water management within the villa.
