Da «funzioni utili alla società» a uso sociale del patrimonio architettonico: progetti promossi dal Terzo settore e attualità della Carta di Venezia

By promoting the use of monuments in functions useful to society, the Venice Charter assigns reuse a fundamental role in guaranteeing the conservation of the architectural heritage; at the same time, the document places limits on the transformations that new uses imply, legitimising interventions based on the compatibility of the new functions with the physical characteristics of the buildings. At the end of the 20th century, the evolution of scientific debate led to the definition of new strategies for reuse, in the light of the concept of sustainable development and a vision of the architectural heritage as a catalyst of multi-dimensional value. This implies the need to evaluate the quality of the project according to parameters that are not exclusively related to material respect. The theoretical statements formulated find expression in the projects developed by the Third Sector, which today as-sume great relevance thanks to programme agreements and funding. This paper therefore intends to carry out an examination of the reuse projects promoted by non-profit organisations. Through a comparison with the principles expressed by the Venice Charter, it questions the criticalities that emerge from initiatives that see the participation of the Third Sector as proponent.
