Hall 3 houses artefacts coming from the excavations of Nuraghe Funtana with the identification of the sites of discovery and with a context reconstruction of the last use-phase of the chamber of the central tower, depicted in a poster in the background. The excavation of that layer, documented by images related to the discovery of artefacts, represent an important element in contributing to the knowledge of the Nuragic civilization between the late Bronze Age and the early Iron Age.
The huge collapse of soil and blocks obstructing the room inside the central tower sealed the last life moments of the Nuragic Age. The digging-out process opened a clear laceration during that use-phase on the furniture and the supplies of 3000 years ago and more: a counter/seat along the wall, characterised by 28 blocks having the shape of a truncated pyramid, a fireplace characterised by 7 shaped trachytic ashlars, two exceptional monolithic “small tables” made of calcareous tuff characterised by a circular surface and a truncated cone shaped base and, finally, small bronze objects and ceramic containers.
In the passage between hall three and four, a large panel depicts the most significant and best preserved Nuragic monuments of the territory. Currently, of the numerous examined nuraghes, we have monumental evidence only in certain cases: besides Nuraghe Funtana, object of systematic excavation and restoration works, it is possible to see Nuraghe Sa Domu ' e S'Orku, the corridor type, and Nuraghe Chisti, the single-towered type.
The presence of the sacred spring of Funtana 'e Baule is a clear reference to the religious sphere. We haven’t found any Tombs of the Giants, the typical Nuragic collective tombs; however, the central stele motif, the typical entrance of the tombs, has been engraved inside the rock of a preexisting domus de janas, the Partulesi XIV grave, through a modality widely documented, in particular within the central-northern area of theIsland.
