REWIND: Interactive Cognitive Artefacts for Lost Landmarks Rediscovery

This paper presents a methodological framework for rediscovering lost urban landmarks through web-based interactive cognitive artefacts that combine geolocation, 3D modelling, historical reconstruction, and gamified user interaction. The research focuses on the majolica domes of Naples, once distinctive elements of the historic skyline that were progressively transformed, hidden, or demolished through urban growth, earthquakes, and restoration interventions. Starting from archival documents, historical maps, iconographic sources, and survey data, the authors generate digital twins and level-of-information-oriented 3D models able to visualize changes across time. These models are then integrated into interactive platforms such as Google tools, CAD Mapper, Autodesk Infraworks, and panoramic tour systems, allowing users to compare past and present urban landscapes both remotely and in situ. The selected case study of the Church of SS. Apostoli demonstrates how users can virtually rewind time to observe successive transformations of the dome, including the loss of its lantern and majolica cladding. The research highlights the potential of low-cost digital tools, AR/VR applications, and immersive storytelling to strengthen cultural awareness, public participation, and the perception of urban identity.
