This volume presents an interdisciplinary exploration of cultural heritage conservation, integrating perspectives from architecture, materials science, environmental studies and heritage management. It examines theoretical frameworks, methodological protocols and case studies addressing the preservation of built, movable and intangible heritage, emphasizing the interplay between physical processes of degradation and strategies of prevention and intervention. The structure emphasizes thematic essays rather than a single‑author narrative, reflecting the diverse contributions typical of the series published by the institution. It contributes to the field of heritage studies by offering a broad survey of conservation issues within the Italian context in the early 1990s.
