Grotta Romanelli (Lecce, Southern Italy) Between Past and Future: New Studies and Perspectives for an Archaeo-geosite Symbol of the Palaeolithic in Europe

Caves as geosites structurally illustrate the strict dependence of human occupation on geological and geomorphological process-es, playing a crucial role in the development of human civilisation. Grotta Romanelli embodies such a kind of geosite, being a coastal cave occupied by humans since the Middle Pleistocene and considered a symbol of the Palaeolithic period in Europe. Research on the cave, derived from the excavation activities carried out last century, consisted of a well-documented stratigraphic framework, abundant fossil remains and archaeological findings which included tools and rock art. The excavation activities stopped for about 40 years, hampering any new research on the cave. In 2015, new fieldwork was initiated and the multidisci-plinary team immediately had to face several conservation issues linked to natural processes (erosion, degradation of the walls due to biodeteriogens) and human activities (mainly legal and illegal excavations). The use of 3D technologies to document the different phases of the research, from the field work to the digital reconstruction of fossil remains, has been extensively applied and represents an attempt to solve the issues of accessibility, education and sharing the heritage, which should be further implemented in the future.
