After the research of the 1800s, the Sassello area no longer had researchers who continued the work of Perrando and Rossi.
In fact, the type of findings, scattered over vast areas and lacking the possibility of on-site verification of the presence of sites of greater significance or concentration and therefore worthy of excavations and archaeological investigations, did not make these places attractive to scholars who succeeded one another in the region.
The new phase of research began in 1988 precisely because of this now century-old lack of findings.
Retracing the "paths" of the two illustrious researchers - described in Issel's monumental works "Liguria Geologica e Preistorica" (1892 and 1908) - the Research Group, in close collaboration with the Archaeological Superintendency of Liguria, was able in a short time to find, during surface explorations, a considerable quantity of artifacts that allowed the opening in 1990 of the prehistoric section.
The surveys conducted by the R.G. made it possible to identify new sites that, among other things, express a cultural typology perhaps even superior to that of the last century, thanks to the new knowledge acquired and the involvement of the numerous experts who are now taking an interest in this too often forgotten corner of Liguria.
