Diagnostics and conservation of coastal archeological sites: the case study of the roman villa of Casignana, Reggio Calabria (Italy)

The conservation of coastal archaeological sites, like the Roman Villa of Casignana in southern Italy, dating back to the 4th century AD, faces various threats, including erosion, rising sea levels, and urbanization. To preserve this site’s valuable mosaics, a multidisciplinary approach involving archaeology, environmental science, engineering, and community engagement is necessary. The University of Calabria, particularly through its Restoration academic course and Heritage Science research group, focuses on conserving and valorising the Villa. As part of the national PNRR Tech4U project, the Villa of Casignana has been chosen as a pilot site for the development of innovative technologies for the conservation of cultural heritage, also taking into account the evolution of conservation problems related to climate change and the evolution of coastal lines. Once validated in the laboratory, these technologies will undergo field testing. Community involvement and education are emphasized for the sustainable conservation of coastal archaeological sites.
