The doctrine of conservation, enriched by centuries of multidisciplinary contributions, emphasizes the preservation of cultural heritage and its profound societal relevance. Despite its complexity and diverse perspectives, the doctrine underscores the need to protect cultural and natural diversity from the adverse effects of globalized economic dynamics that have replaced technologies and materials and have contributed to the reduction of available local skills in artisanship. This paper examines how adaptive reuse and circular economy principles can bolster conservation efforts, aligning with the intrinsic mission to preserve embodied energy, reduce resource waste and rely on skilled artisans performing constant care. To this aim, it recalls the contribution of the CLIC project, which advocates the need for innovative economic models that integrate conservation values, promoting sustainability while addressing contemporary challenges. It stresses the importance of establishing robust governance frameworks, extensive education, and supportive legislation for effective heritage preservation. It concludes by placing emphasis on local awareness, creative conservation methods, and the experiential dimension of heritage, ensuring cultural assets are maintained and utilized responsibly, as well as asks for future efforts to balance development pressures with the imperative to preserve cultural narratives, recognizing heritage as an invaluable capital that enhances societal well-being and resilience.
