Serra San Bruno e la sua certosa. Rilievi digitali e percorsi di narrazione interattiva.

The paper presents the results of research dedicated to the documentation and digital enhancement of architectural and artistic elements from the Certosa di Santo Stefano del Bosco in Serra San Bruno (VV, Italy), one of the most significant monastic complexes in Calabria, severely damaged by the 1783 earthquake. The dispersal of the charterhouse’s materials and their relocation within the urban fabric of Serra San Bruno after the earthquake made it necessary to develop digitization and interactive storytelling strategies aimed at restoring continuity and intelligibility to this important heritage site. The research unfolds along two complementary lines: firstly, the creation of the SerraVT project - an interactive map that integrates digital surveys, ground- and drone-based spherical imagery, historical data, and archival documentation within an open and multidimensional information ecosystem; and secondly, the design of the CARthusian augmented reality application, conceived for in situ exploration of the displaced fragments. The latter is based on laser scanner and Structure-from-Motion surveys and has been implemented on the Unity platform using Vuforia Area Target technology. Both systems adopt interactive and augmented heritage communication models that move beyond mere visual representation to promote experiential and critical knowledge. The surveys of the ruins of the Certosa and of the dispersed artifacts provide the foundation for digital reconstruction and for defining new interpretative frameworks of the charterhouse’s heritage. The integration of three-dimensional surveys, historical data, and XR technologies has led to the definition of a replicable methodology for enhancing contexts characterized by material dispersion and historical stratification, offering broader insights into the role of digital platforms in the transmission of memory and the shared construction of knowledge.
