Digital Valorisation and Fruition for the Knowledge of Fortified Architecture with Limited Accessibility: The Case of Moliterno Castle, Italy

Fortified architecture plays a central role in national heritage but is often marginalised by structural constraints and limited accessibility. Through the case study of Moliterno Castle, this research proposes a methodology that extends the “knowing in order to conserve” paradigm towards inclusive digitisation. Historical analysis and photogrammetric survey are integrated to produce a high-precision 3D model conceived not merely as a geometric replica but as a narrative of architectural evolution. Implemented in the open-source ATON framework, the model supports an interactive Web3D environment in which semantic content helps overcome physical barriers and reconnect the monument with its landscape and community
