La conservazione dei monumenti naturali

This article addresses the conservation of natural monuments, particularly geosites and anthropized caves, within the framework of international and Italian legislation on cultural, natural, and landscape heritage. Drawing on the UNESCO World Heritage Convention (1972) and the European Landscape Convention (2000), it highlights how natural monuments, understood as geo- logical formations of outstanding universal value, are integral to collective cultural identity, resulting from the long-term interac- tion between natural processes and human activity. Despite an extensive regulatory framework, the material conservation of rock formations, cliffs, natural arches, and caves remains insufficiently explored and is often approached mainly through geotechnical engineering, with limited attention to restoration theory. The article emphasizes the need to apply conservation principles such as minimum intervention, compatibility, and respect for authenticity to consolidation works. Particular focus is placed on caves with archaeological or artistic significance, where geological structures, architecture, and figurative art coexist and require integrated, interdisciplinary conservation strategies. Through the analysis of decay processes, environmental dynamics, and selected case stud- ies, the paper advocates for a collaborative approach combining geotechnics, restoration, diagnostics, and monitoring to ensure the sustainable preservation of natural monuments.
