The memory of a strong religious tradition dating back to late antiquity and epigraphic findings of great importance - the oldest memory of epigraphs from San Calocero dates back to the 15th century - have helped to keep the interest in this site, which was definitively abandoned, alive in the ingauna community. in 1593, when the Clarisse nuns moved within the urban context to the district of Santa Eulalia (now the old hospital).
We owe to Nino Lamboglia (1912-1977) the first explorations of the site in 1934, continued with the significant campaign of 1938-'39 and in 1971. This great archaeologist, who did his utmost to spread and extend to classical and medieval archeology the stratigraphic method in the excavation investigations, in the San Calocero he made the first experiences of stratigraphic archeology.
