The paper presents the Heritour project, an integrated framework combining artificial intelligence, sensor-based monitoring, and extended reality technologies for the management and promotion of cultural heritage. The approach focuses on the development of a predictive monitoring system based on machine learning algorithms, capable of processing data collected through IoT sensors and integrated surveys to assess structural conditions and potential risks. At the same time, the project leverages XR technologies (VR/AR) to enhance dissemination, enabling immersive and interactive exploration of heritage sites. The workflow integrates data acquisition, processing, and management within a multi-layered digital infrastructure, supporting both decision-making processes and public engagement through semantic 3D models and digital platforms.
