Extending 200 thousand square metres and surrounded by lush cork oak trees flanked by the Mediterranean scrubland of the Gerrei hills, it is one of the most evocative and significant archaeological sites in Sardinia. A few kilometres from the town of Goni, along the provincial road to Cagliari (just half an hour from the capital), is the Pranu Muttedu park, an extensive platform of arenite and schist, on which stands a vast pre-Nuragic monumental complex, ‘divided’ into a number of agglomerations. In the locality of Crancu to the north is the agglomeration of the hut of reference of the necropolis. To the south of the village are the burial grounds of Pranu Mutteddu and Nuraxeddu, exceptionally surrounded by large groups of menhir pairs in alignment or inside the tombs themselves, and from round constructions likely of a sacred nature. Excavated in rocks further south stands the Domus de Janas necropolis of Genna Accas, consisting in three tombs. Other structures arise in the area, with the remains of the Dolmen ad Allée Couverte di Baccoi being of particular interest. The exceptionality of the site also derives from the highest concentration of menhirs known in Sardinia, with around 60 variously distributed, be it in pairs, in alignments or in small groups, sometimes in the same tomb architecture. They are of the ‘proto-anthropomorphic’ type, with an ogival shape and a flat anterior surface.

The sepulchres consist of two or three concentric rings of stones, sometimes with a frontage in echelon to support the mound. At the centre is the funeral chamber, which is accessed through a corridor formed by orthostatic slabs, covered with lintels. The cellae within are circular or elongated, depending on how many sepulchres are housed inside. The coverings were tabular or pseudo-inverted. The grandiose Tomb II has an entrance, an antechamber and a funeral cella that have been excavated in two distinct rocky blocks, carefully set down and arranged, with fine workmanship and an architectural design that recalls the Domus de Janas sepulchres. The excavations revealed miniature pots, arrowheads in obsidian and various other objects, including a flint dagger and a white stone hack. From the artefacts, we can trace the complex to the late Neolithic period (3200-2800 BC) with late ‘assimilations’ through to 2600 BC.

The park is equipped with services, including an introductory area to the excavations, equipped with multimedia tools to guide users throughout the visit accompanied by guides, with the option to stop for refreshments and to enjoy the local cuisine.
