Qualche cenno sull'argomento:
Tuvixeddu hill hosts a Punic necropolis, which has been considered the widest and most significant one in the Mediterranean area since the XIX century. The necropolis still preserves most of its striking expansion, although long damaged by the working of the quarries, which supplied the cement factory. The declining part of the hill pointing to the lagoon (where the city of the living arose) is covered by a thick succession of burial chamber cavities, made of a drop shaft, with a mean depth of about 3 meters, giving the access to the real burial chamber dug upstream, where one or more dead people were placed with the grave goods (pitchers, dishes, oil lamps) and, sometimes, personal objects (beetles, glass-paste necklaces, differently shaped amulets). A slab then closed the door of the cell and the drop shaft was filled up with heaps of stones produced through the excavations.
The underground tombs were used from the VI to the III century B.C.. For a short time during the Roman Empire, a small part of the area was used for extracting building stones: the quarry, whose cuts in steps and the stacked blocks are still visible, was later crossed by the Roman aqueduct, approximately in the II century A.C.. During the Second World War the Tuvixeddu necropolis hosted many people who had their houses destroyed by bombs, in a long lasting poor state even after the end of the war.
The scientific importance of the necropolis emerged particularly thanks to Antonio Taramelli’s research, a Monument curator in Sardinia in the early 1930s, with Predio Ibba dig, the first on the hill, conducted on a wide surface through strict and scientific criteria. The survey starting in 1908 involved 180 hypogaeums located upstream the former school building, nowadays the district headquarter. He rediscovered 350 objects: coroplastics, Punic and Attic ceramics, balm containers made of glass paste, small faïence containers (a particular and polished enamelled ceramic) created by the Egyptians, bronze razors, jewelleries, necklaces with vaghi made of steatite and pastiglia, beetles with Egyptian and Greek characteristics.
