This paper presents a digital heritage strategy aimed at documenting, enhancing, and disseminating the religious cultural heritage of the Naples metropolitan area through a web-based geographic platform and immersive virtual tours. The research develops an open and updateable GIS database that maps churches and religious buildings using typological, morphological, historical, and descriptive data, later published as an interactive WebGIS environment. As a detailed case study, the Church of San Giacomo Apostolo Maggiore in Casalnuovo di Napoli was surveyed through integrated reality-based technologies, including terrestrial laser scanning, UAV photogrammetry, and close-range photogrammetry for decorative details. These datasets were merged into complete three-dimensional models and used to generate drawings, documentation, and equirectangular scenes for a browser-based virtual tour built with Marzipano. The tour includes navigable panoramic environments, hotspots, technical drawings, and embedded 3D altar models. The study demonstrates how lightweight digital tools can improve remote and on-site accessibility, strengthen public awareness, and create a scalable model for the valorization of hidden religious heritage.
