Necropolis of Anghelu Ruju

The Necropolis of Anghelu Ruju is the largest pre-Nuragic necropolis in Sardinia, located north of Alghero in the Province of Sassari, Italy. Discovered in 1903, this extensive archaeological site contains 38 domus de janas, or rock-cut chamber tombs, that document continuous use from the Late Neolithic through the early Bronze Age. In 2025, the site was inscribed as a UNESCO World Heritage Site as part of the serial nomination "Prehistoric Funerary Practices in Sardinia, The Domus de Janas."

The necropolis was discovered accidentally in 1903 during excavations for a farmhouse on the Sella and Mosca winery estate, when workers found a human skull and a tripod vessel. The archaeologist Antonio Taramelli conducted the first systematic excavations in 1904, uncovering ten domus de janas with graphic documentation by Nissardi. Taramelli returned in 1908 to discover 21 additional tombs. In 1936, Doro Levi identified four more tombs, designated A through D to distinguish them from Taramelli's numbered sequence. Ercole Contu discovered three further tombs during restoration work in 1967, including Tomb VIII bis and Tombs E and F. Giovanni Maria Demartis worked at the site between 1904 and 1995. The site was carefully restored and enclosed with fencing during the 1990s.

The archaeological finds from Anghelu Ruju span at least 1,500 years of use, from the Late Neolithic to the early Bronze Age, encompassing five distinct cultural phases: the Ozieri culture (3200-2800 BC or 3400-2700 BC), Abealzu-Filigosa, Monte Claro, Bell Beaker (Campaniforme), and Bonnanaro cultures. The grave goods include pottery, hypothesized "mother goddess" statuettes, weapons, necklace beads, flint tools, mace-heads, arrowheads, and axes. Items of foreign origin are particularly significant: copper daggers apparently from Spain, an awl likely from southern France, a copper ring of eastern European style, and an axe from the British Isles, alongside local Sardinian obsidian from Monte Arci. Silver rings were found in six tombs. The finds are now housed in the National Museum of Cagliari and the Museo Nazionale G. A. Sanna in Sassari. Anthropological studies identified two main human types: a majority dolichomorphic indigenous population and a minority brachymorphic type associated with Bell Beaker bearers, with an average male height of 1.62 meters. A 2020 archaeogenetic study revealed ancestral components linked to western hunter-gatherers and early European farmers, with a notable outlier individual of North African genetic profile from the Chalcolithic period.

The site is distinguished by its exceptional rock-cut architecture and symbolic decoration. The tombs feature carved architectural elements including architraves, pillars, pilasters, columns, and bases, as well as magical-religious motifs such as false doors, petroglyphs, and traces of red pigment. The most striking decorative elements are the numerous carvings of long-horned bull heads (bucranes), found in and around at least three tombs, notably in Tombs A, XIX, XX bis, XXVIII, and XXX. Tomb XXVIII contains particularly well-preserved reliefs: two protomes on the back wall of an ellipsoidal chamber, with the right one featuring double arched horns above a rectangular head containing two concentric circles carved with a small pick. These bucranes have been hypothesized to support "Mother Goddess" theories and to suggest a solar cult. The tombs contained remains of between two and 30 deceased, including children.

The necropolis occupies two distinct zones beside the Rio Filibertu stream: a flat rocky outcrop with seven tombs, and the flanks and summit of a modest hill at 23 meters elevation containing the remaining 31 tombs. The local stone is a soft, compact sandstone that facilitated carving with coarse stone picks found in large quantities within the tombs, but also limited vertical development. A near-surface sand layer forced builders to create thin ceilings, many of which have collapsed, leaving numerous tombs open to the sky. Modern quarrying activity severely damaged the southwestern sector, particularly Tombs A and XX bis. The tombs are all hypogea, accessed either by vertical shafts or descending dromoi with carved steps, generally oriented east or southwest. The architectural typology varies considerably: shaft-entry tombs tend toward irregular plans with rounded or oblong cells, while dromos tombs feature more symmetrical, regular plans, often developing transversely in a classic "T" pattern. Tomb III contains eleven chambers, the maximum at the site, while Tomb XXVI is uniquely unicellular. The site was spontaneously developed without regular planning, yet no tomb ever encroaches upon another, demonstrating exceptional spatial management by the builders.

The Necropolis of Anghelu Ruju is located in I Piani locality, north of Alghero, alongside provincial road 42 dei Due Mari at kilometer 21+390, approximately 10 kilometers north of the city and north of the turnoff to Alghero Airport. The site lies within the metropolitan area of Sassari on the island of Sardinia. It is enclosed and accessible to visitors, managed with the website http://www.coopsilt.it. The nearby Sella and Mosca winery produces a fortified red wine named Anghelu Ruju after the original landowner whose estate contained the discovery. The nearby Domus de Janas di Scala Piccada provides an additional related site in the vicinity.
