Digital preservation and archaeoastronomical insights: 3D digitization of megalithic heritage in the Maltese Archipelago

This paper presents the integration of advanced 3D digitization and visualization technologies in the study and preservation of prehistoric megalithic heritage sites in the Mediterranean. We focus on the digital documentation and analysis of the Borġ in-Nadur megalithic complex and other notable sites, employing a combination of terrestrial laser scanning, aerial and terrestrial digital photogrammetry. The research highlights how digital tools not only enhance the precision of archaeological documentation but also promote virtual accessibility and offer new insights into the archeoastronomical significance of these structures. We discuss the production of high-resolution digital replicas, their utility in virtual reconstructions, and the role of digital platforms in public engagement and scholarly study. The findings underscore the potential of digital technologies to revolutionize heritage conservation and research, providing a comprehensive digital approach to the safeguarding and understanding of our ancient heritage.
