Work again concentrated on the western sector of the summit of Monte Tezio, extending the excavation area and, in particular, deepening the excavations from the previous campaigns. This led to a clearer definition of the enclosure’s perimeter, despite the fact that it was largely lowered, with respect to its original height and flattened by collapse and land slippage. The bad state of preservation was also due to its substantial instability. Several new stretches of “facing” came to light along the south-western edge of the excavation area. These were constituted by large limestone slabs fixed vertically into the ground, functioning as containment for the thick walls to the rear. These walls comprised dry-stone built structures and embankments. The construction of the wall attests great ability, from the arrangement in sequence of the various stone components, to the line itself, which uniformly followed the summit edge, progressively re-entrant and convex, even though only surviving at ground level and in discontinuous sections. Inside the perimeter wall, the excavation revealed a just as ingenious arrangement of cobbles and mediums-sized slabs, similarly fixed vertically in the ground. In the absence of postholes, this arrangement probably served as the base for the supporting elements of timber walls. Hearths characterised by substantial concentrations of pottery and animal bones were found in association with the cobble and slab structure.

The 2011 campaign confirmed the prolonged occupation phase on the hill summit. The finds were almost exclusively pottery and occasional bronze artefacts (however, as documented in 2009, with increasingly frequent exceptions: mainly large decorated pins), glass paste and even more rarely iron. They provide a chronological horizon, beginning in the final phase of the Bronze Age and continuing into the early Iron Age.
