Abstract:
This paper proposes a structured and replicable protocol for the development of virtual tours in hybrid heritage sites, where indoor and outdoor environments co-exist and present specific challenges for documentation and interpretation. Drawing on a pilot project at the Norman Castle of Aci Castello (Sicily, Italy), the methodology integrates photospheric acquisition (Matterport Pro2), photogrammetry, and multimedia storytelling within a topographically inspired navigation model. The digital experience was further enhanced through the use of third-party software (3DVista), enabling improved interaction, media layering, and accessibility. The results demonstrate the effectiveness of a hybrid workflow in reconstructing spatial continuity, articulating historical complexity, and supporting inclusive engagement. Although user testing is ongoing, the protocol offers a transferable framework for the valorization of other large and mid-sized archaeological and architectural sites, contributing to the broader discourse on sustainable digital heritage practices.
