In the third field season the excavations carried out in the previous years were extended, both in the central part of the site and in the area of the circular element which had been identified previously.

The investigations had demonstrated that the entire central area of the settlement was greatly disturbed by ploughing. In fact the uppermost layers identified by the excavations consist of the remains of a deposit most of which had been removed in the past. These are organic layers with a high proportion of archaeological finds, although lacking any useful elements for the reconstruction of the stratigraphy. However, beneath these deposits the excavations revealed the most recent occupation levels of the site, characterized by post holes, arranged in a north/east-south/west orientation. Beneath these deposits, the excavations identified evidence which seems to represent the latest frequentation of the site, characterized by post holes which, on the basis of the evidence so far, are also arranged north/east – south/west. Therefore the recent results confirm that which had already emerged from earlier field seasons, in other words that this frequentation follows a consistent levelling of the area with gravel fills. To the east of the post holes, a fill and the cut of a large robber ditch was identified on the basis of the presence of lime and mortar in the layer of the fill. This has no direct relationship with the earlier stratigraphy, and moreover can still not be related to a precise relative sequence.

However, it seems to be clear that this was a foundation or robber trench represents the perimeter of a great quadrangular structure (only partially brought to light) oriented east-west and located exactly at the centre of the hill. Inside the structure some hearths have been identified, with burnt earth and much charcoal and burnt bone, Although it is impossible to hypothesize as to the nature and function of this structure, the topographic relationship with the rest of the settlement should be highlighted, in particular the relationship with the smaller circular element which occupies more than half of the internal space.

As regards the defensive structure, the 2009 season has recovered important information which confirms the existence, at least in one phase of its use, of a walled circuit, characterized by a thick cement foundation and whose walls may have been in perishable material. In the area outside this wall the 2007 field season discovered the remains of a robber trench/foundation of a hypothetical structure. This season has identified the clear remains of the perimeter of the structure, which unfortunately is only partially conserved (a little more than half). Part of the northern and southern walls of the structure have been identified, and the entire western wall (6 metres long): within the perimeter various layers relating to a series of beaten earth floors have been identified, con silt sediments, and layers of lime and sand which are often reddened. This context, therefore, demonstrates the frequentation of the circular strip between the internal walled circuit and the intermediate “circle” identified by the excavations. Precisely at the point linking these two circles, as in those larger examples on the exterior, in the final days of the excavation two small trenches were opened, aimed at clarifying the nature and the depth of the conservation of the deposit. Rather than indicating the presence of two distinct elements, they suggested the existence of a single great circular ditch, of which the two large circles identified by the excavations represent the two edges..
