Since 1994, the Centre d'Études Alexandrines (CEAlex), a research unit operating under the aegis of the CNRS, has been leading extensive studies of this complex submerged site with an international team of underwater archaeologists. Due to the scale of the work, scientists initiated a photogrammetry program in 2009 for studying and potentially reassembling the archaeological fragments. This effort expanded in 2013 with the creation of a digital twin of the entire site. Digital technologies have profoundly transformed the scientists' work, both in the field and during post-excavation analysis, opening new avenues for site analysis and research perspectives.Attribution 4.0 International License10.2312/dh.202532734 pages
