The excavation of structure 6 continued: see the 2010 entry for a synthesis of the stratigraphic sequence and interpretation.
Work continued on US9, begun in the last campaign, a horizon of grey silty sediment containing abundant pottery and charcoal. The levels of the individual finds was documented by three- dimensional positioning. Together with the pottery, the layer also produced occasional faunal remains and stone objects, including three perforated limestone “buttons”. Abundant charcoal and some carbonised seeds were recovered from the floatation of US9 in its entirety.
Once the removal of US9 was completed, the materials from the edge being recorded as US9a, the contours were recorded using Close Range Photogrammetry.
At this point excavation of the latest structure, cutting the archaeological deposits below, was considered complete. The suggested reconstruction of its history is as follows:

On the west side of the hill of Bibbiani, at some time during the recent Bronze Age or slightly earlier, after partially terracing the surrounding area, what was probably a dwelling was built inside an artificial ditch about 14 m long and 5.5 m wide. The ditch was cut into the bedrock, constituted by sandstone with a rather friable roof. The structure was occupied continuously or with only brief interruptions, as attested by numerous occupation levels and “restructuring” visible along the western edge of the structure. At some time during the Late Bronze Age, more substantial restructuring took place involving the excavation, within the fill of the pre-existing structure, of a ditch circa 7.50 × 3.00 m and 50 cm deep. At the same time, the structure’s western margin was presumably levelled, exposing the early fills. This new ditch was on a slightly different axis compared to the other.
The fills in the new ditch are interpreted as follows:
US9 occupation level;
US8 abandonment phase;
US7 (a-b-c-d-e-f) collapse of a hypothetical containing wall uphill from the dwelling;
US6, US4, US3 colluvial phases.
The colluvial US3, at an undefined moment, was in turn partially eroded away, a phenomenon also involving the north-western part of the structure. US3 was sealed by US2, which was deposited no earlier than the 14th century, given the presence within it of archaic majolica.
