The megalithic collective burial of S'Ena 'e Thomes (figs. 1, 2), a dolmen structure with an arched stele on the front of the tomb, is a remarkable example of Nuraghic funerary architecture.

Although only a few artefacts have been found, mainly various ceramic shapes known in the Bonnanaro Culture (pan, cup, rounded bowl, multiple-foot vase, olla), its construction dates back to the Middle 1 Bronze Age (about 1600-1500 B.C.). Overall, the grave is more than 16.20 metres long. The entrance to the tomb faces south. The semi-circular area in front of the tomb, the exedra, consists of two wings on each side of the entrance and is marked by slabs driven knife-wise into the ground at the front, decreasing in size towards the centre, which delimit the enclosed ceremonial space where the funerary ceremonies were carried out (fig. 3).

The impressive arched stele located at the centre, with a height of over three metres and a width of at least two, carved from a single block, with a curved profile on top, surrounded by a frame in relief and a transverse listel, constitutes the most interesting element of the burial site (fig. 4).

At the bottom there is a small squared door with rounded corners and through this it is possible to enter the rectangular burial chamber (fig. 5), built by using granite slabs placed knife-wise into the ground, on which a row of stones rests and above which the roof was positioned, obtained by employing large slabs placed horizontally on the orthostats. Of these, three were still in their original position whilst two others were found upside down at the side of the grave. The floor of the room, affected by illegal break-ins, consisted of stone tiles.

It was excavated and restored in the late seventies of the last century.

The excavation work brought to light a few artefacts which document attendance of the monument, or at least of the area where it stands, from the Bronze Age until Roman Times and the Middle Ages (III century B.C.-VI/VII century A.D.).
