The tomb of Bingia ‘e Monti is located in the countryside of Gonnostramatza about 2 km from the town and was discovered during the excavation of the nuraghe of the same name in 1990; it dates back to the Copper Age and was used until the Early Bronze Age. Irregular/rectangular in shape, it is partly dug into the rock and for a second part built with 4 large parallelepiped basalt ashlars joined together in pairs by dry stone walls. The covering of the tomb has not been preserved, but it is assumed to have been of the flat-bed type, that is, obtained from stone slabs placed horizontally. This type of burial is called hypogeic-megalithic, emphasizing the mixed technique of rock excavation and construction with large boulders.
The uniqueness of the tomb lies in the fact that the excavation returned a gold necklace, an object that has no equal in all of prehistoric Italy. Buried within the tomb were at least 96 individuals of various ages, both male and female, and one of these had undergone a “surgical” operation called cranial drilling in his lifetime, meaning that a portion of his skull had been removed and he had survived this operation.
