The specchia is a real monument that, with its length of 60 meters, it is among the most impressive prehistoric monuments of the Mediterranean. Below the usual accumulation of calcareous stones that distinguish these archaeological evidences, several tombs are preserved, with equipments which allowed the definition of their chronological context. The structural characteristics of the tombs permit to comprehend the degree of expertise and sophistication achieved by this civilization: these graves with units in lithic slabs in which the interred was placed with her trousseau ( a pottery typical of the Bronze Age, or jugs and bowls of various sizes). The size of the units and the presence of access corridors permit to define what real "burial chambers" are. An important information on the complexity of the tombs is the construction of the pavement, achieved by a layer of earth that had the function to stabilize the underlying bedrock, on which a slab of stone was placed, which served as the pavement of the tomb.
