The excavations carried out in 1988-1993 and 1997-2006 at the site of Colle Santo Stefano near Pozzo di Forfora (Ortucchio, L’Aquila); the dig involved an area of about 250 square meters. The Early Neolithic set of layers was up to 90 cm deep and included areas and structures referable to subsequent phases of development of the inhabited area. The oldest structure (phase I) is a sub-rectangular surface, consisting of small to medium-sized pebbles infixed thickly into a layer of lake silt spread on the gravels of the substrate. A ditched elongated structure, oriented East-West, indicates a reorganization of the inhabited area (phase II). It cuts down the underlying deposit reaching the gravels of the substratum and it can be interpreted as foundations of an elevated construction. A hearth and a circular cavity delimited by stones and containing fragments of a zoomorphic vase, belong to the same phase. The qualitative and quantitative study of the pottery allowed to define the characteristics of the production, dating it back to the contribution of human groups coming from the Southern area of the Italian peninsula, as well as to identify a process of transformation during the existence of the village, which is evident from a diminished interest in the technological and decorative elements characteristic of the Southern area and from the acquisition of specialized production technologies, perhaps related to contacts with the Tyrrhenian area. The corpus of Colle Santo Stefano allows to reconsider the broader issues concerning the Neolithisation process along the middle Adriatic coast of the Italian peninsula, to discuss hypotheses about the development of the two aspects of Impressed Ware (one with a Southern affinity, the other traditional), as well as to specify the relations with the middle Tyrrhenian area. On the basis of the data, these two aspects differ at the territorial level and they are at least partly chronologically different as indicated by the radiocarbon dating at Colle Santo Stefano of samples taken from various levels of the deposit.
