The historic city project is the most important contribution made by Italy to international research in the field of architecture and town planning. It has become a theoretical and practical model that has spread around the world and that has been adopted by international institutions. This exhibition pays tribute to the work of Leonardo Benevolo, the leading light behind the creation of this project. The show brings up to date the content of the “Esportare il Centro Storico” exhibition, which illustrated how the physical protection of historic centres has developed and how it will be continued in future.
