This settlement of eight to nine hectares was first occupied in the Bronze Age and is placed close to the later small Villanovan cemetery at Chiusa Cima, which may be better connected to another poorly researched settlement on Monte Cuculo. In common with other sites in the general area, such as San Giovenale, there are discussions about the degree of direct continuity between periods of occupation. Whatever the resolution of these issues, there was clearly an Archaic Etruscan settlement on the site accompanied by famous rock-cut tombs, where the age of grave goods ranges from the seventh to the third century BC, concentrated in the sixth century BC. There are strong connections between the internal architecture of the tombs (e.g., plan and couch types), the grave goods (storage jars and braziers) of San Giuliano, and those of Caere (as is also the case with Blera and San Giovenale). This suggests that the settlement was politically subordinate to Caere for most of its occupation. There is also a late votive deposit on the site.
