The paper intends to explore the integration between Scan-to-BIM parametric modelling techniques and VR virtual systems to support activities of documentation, analysis, valorization, and popular storytelling of Architectural Heritage. In this sense, these themes have been deepened through a series of experimental HBIM applications conducted on the military fortifications of Piombino, and more specifically, on the case study of the defensive complex formed by the Rivellino and the Porta a Terra. Through the implementation of the HBIM model within game-engine platforms, the project aims at enhancing the historical heritage, favouring dissemination and interactive use through immersive virtual environments.
