In 2019, work took place in the western room of structure 9 (room B). The removal of the first layers of humus revealed part of an original stone floor preserved in the south-western part of the room. This differed from the floor documented in room A, which was a simple beaten earth surface. Underneath the paving, there were several layers of earth and stones with small and medium blocks that contained abundant pottery fragments, the majority of which could be dated to the Nuragic period. This material was clearly out of contexts as it was of later date and constituted by fragments of coarse ware cooking pots datable to between the 5th and 6th centuries A.D., coherent with what was recorded in room A during the 2018 campaign. The layers in question were interpreted as deposits of materials, probably deriving from ruins or the demolition of earlier structures, which were used to raise the floor surface for the construction of structure 9, as the latter, in the area occupied by room B, was at a lower level than its eastern part.

Work also took place in the new sector of the excavation (Sector 1 – Area 3000) opened in an area of the site that has never been previously investigated. This is the south-western part of the archaeological complex, which is thought to be a late antique/early medieval necropolis where a number of burials in stone coffins were uncovered by clandestine excavations in the past. Following the removal of the grass and an accumulation of very small stones, the result of modern stone clearing, a series of alignments of straight and curved walls emerged that clearly indicated the presence of buried structures. Among these, there was a structure with a double facing built of medium and small basalt blocks, sub-circular in plan with an external diameter of c. 2 m. Inside the structure a beaten earth surface (US 3008) was uncovered, which overlay an arrangement of small stone slabs and broken tile forming a sort of paving (US 3014). Based on comparisons with similar structures found in early medieval funerary contexts e.g. Sant’Imbenia (Alghero), Santa Filitica (Sorso) and Santu Miali (Padru), this has been interpreted as a construction linked to cult functions, and the rites of refrigeria in honour of the deceased. As regards the chronology, thus far the excavation data has not provided any precise indications. The above mentioned parallels provide an ample chronology ranging between the 5th and mid 9th century A.D. The continuation of the excavations across the whole of Sector 1 during the coming campaign should provide more data regarding the chronology and function of this structure.
