The contribution reports on a research concerning the preparatory investigation of some fortified systems of Tanaro Valley (Piedmont) in view of their restoration. The research highlighted the strong connection between the castles and the memory of events and characters that were linked to these architectures; the relationship between landscape and ruins that, today, represents a potential resource for the territory; the willingness of local authorities to improve knowledge, protection and enhancement of this heritage; the need to investigate theoretical and methodological issues and define the proper procedures for the conservation, restoration, safeguard, maintenance and management of a widespread and vulnerable heritage. The study, taking advantage of interdisciplinary contributions, used innovative instruments for the survey and monitoring of this heritage, as well as graphic and digital restitution techniques to propose to the scientific community –and communicate to the native population– the interventions of restoration, conservation, enhancement and management of these fortified systems. The research demonstrates that particular attention has to be paid to these less-known historical architectures that can however contribute, as effectively as the most famous and eye-catching fortification systems, to the political and social development and to the historical identity whose recognition, preservation and valorization are strongly hoped for.
