The necropolis of Su Murrone is an archaeological site located at the foot of Mount Cucullai; it is part of the territory of Chiaramonti, province of Sassari, from which it is about eight kilometers away. It was identified in the late 1960s by archaeologist Ercole Contu and later investigated by the Soprintendenza ai Beni Archeologici di Sassari e Nuoro. The burial site is dated between the 4th and 3rd millennia B.C. It was frequented during the Neo-Eneolithic phases of Ozieri, the Eneolithic, the Early Bronze Age until the Roman Age. The necropolis stands on a trachytic slab and consists of three domus de janas of multi-cellular type with long dromos entrance. The most important, Tomb I, features a small rectangular antechamber that leads into the main chamber from which, in a radial pattern, six other cells branch off. The tomb is characterized by the presence of red traces on the walls and the ceiling in which, carved in relief, a double-sloped roof complete with main beam and 28 rafters perpendicular to it is depicted. Other ornamental motifs, consisting of cornices and pilasters, include a pair of taurine protomes reproduced in relief on the walls of the central chamber, symbolizing the god Taurus or fertility.
