Egypt's sunken ancient cities have been the fieldwork project of the European Institute for Underwater Archaeology (IEASM) since 1992. Franck Goddio discusses key finds and the creation of Oxford Centre for Maritime Archaeology. Franck Goddio, president of the European Institute for Underwater Archaeology (IEASM) and Damian Robinson, director of the Oxford Centre for Maritime Archaeology (OCMA) talk about the foundation of the OCMA in 2003 with the support of the Hilti Foundation in order to create a centre of expertise for Maritime Archaeology at the University of Oxford. Goddio and Robinson discuss the Centre’s achievements that are the result of their long term collaboration. They present fascinating discoveries from the ancient sunken cities of Thonis-Heracleion and Canopus off the coast of Egypt and the Portus Magnus of Alexandria and its sunken royal quarter. These range from artefacts to shipwrecks, port structures and the remains of buildings and temples. The episode also gives insights into future projects of the research team and the development of maritime archaeology using the latest technology, including AI.
