In this territorial organisation, it seems that Saturo had a religious function above all: already in the VII century B.C. there were two important sanctuaries, one located on the promontory (sanctuary of the Acropolis), the other in the valley north of the Bay of Saturo (known as sanctuary of the Sorgente). However, with all probabilities, Saturo was never the seat of a city. The remains of a small settlement (consisting mostly of drainage channels and recesses for wooden structures), served by a carriage road and dating back to the VI century B.C., have been identified on the plateau next to the Sanctuary of the Sorgente. In addition, some contemporary burials were found nearby and are probably connected to the settlement.

The presence of the sanctuaries certainly stood as a pole of attraction also for other Greek settlers engaged in agriculture who probably inhabited farms or small villages in the area. Some necropolises found around Saturo and the chamber tombs discovered on the plateau next to the sanctuary of the Sorgente would confirm this hypothesis.

The Greek presence in Saturo dates back to the III century B.C.
