The course aims to present and discuss current experiences and challenges relating to the conservation of the 20th century heritage. Despite the growing recognition of the cultural significance of modern architecture, there are still challenges to be faced to ensure its protection, since this legacy is constantly threatened not only by natural hazards but also by abandonment and poor maintenance. This heritage must be brought back to life, respecting the spirit of its original characters and maintaining an adequate level of structural and seismic performance. Furthermore, the materials and construction techniques used present serious problems of durability. Indeed, concrete has been widely used during the 20th century, along with other experimental or new building materials that, in most cases, have not aged well. The definition of protocols on conservation principles that should be applied to sites and places of the 20th century is still ongoing and is periodically enriched on the basis of the direct experience of researchers, professionals and institutions. While many challenges and issues are still open, this course aims to raise awareness of the challenges in conserving an endangered heritage, showing the current debate and ongoing research in various parts of the world. The comparison between different points of view and interdisciplinary collaboration will enrich the framework of possible research and communication scenarios in an area of conservation that has only recently started to be addressed.
