A Multidisciplinary Approach for the Conservation Design of the Medieval Fortress of Vogogna from the Analysis to the Valorization of the Archeological Site

Preservation design is characterized by high interactions among different skills, including both architectural and engineering field. When the architectural heritage is composed of the ruins of a medieval fortress, the contribution of archeological studies is fundamental to recognize the different construction phases of the building. This work presents the most recent stratigraphic analyses conducted on the fortress of Vogogna, a military masonry castle in Ossola Valley, Piedmont, whose origin is lost in time and provides further sup-port to define the correct interpretation of the architectural artifact. Previous studies showed several shortcomings concerning the historical evolution of the structure and a precise geometrical survey. The authors developed a geometrical model of the archeologi-cal site, through advanced survey techniques, and analyzed the historical maps of the ca-dasters to investigate additions and transformations of the abandoned fortress and its connection with the rural and natural surrounding fields. The updated information pro-vided new indications for the past uses of the building, and the digital model allowed further considerations on the geometrical characteristics of the structures, addressing some choices for the final reuse proposal for the site, today at the center of a wider project to enhance the cultural heritage in the Vogogna area.
