The archaeological site is located on a plateau of volcanic origin overlooking the northwestern shore of Lake Omodeo, in the area of the Abbasanta plateau, in central Sardinia.
The complex consists of a nuraghe, a village and two tombs of giants. Numerous domus de janas have been excavated at the base of the relief.
The nuraghe is a three-lobed building on which a sub-trapezoidal body rests in the quadrant exposed to O. The original nucleus is represented, perhaps, by this last building, which, developing along the SO-NO axis, constitutes the western part of the complex. The structure, lacunated by the collapses and surrounded by dense vegetation on the O side, has - in the NO quadrant - a sinuous profile.
The SW side, the best preserved one (m 11.5 x m 5 max.), is built with horizontal rows of irregular medium and large basalt blocks. The poor state of conservation prevents the identification of the entrance to the building and the articulation of the interior spaces. However, the sub-trapezoidal shape leads us to consider it a corridor nuraghe (end of Old Bronze - beginning of Middle Bronze).
The three-lobed nuraghe (Advanced Medium Bronze-Recent Bronze-Final Bronze) shows a concave-convex pattern. The entrance to the complex perhaps opened into the straight wall on the SE side, in the section between the two corner towers. Of the O-facing tower, with a circular plan, only a short section of the external wall wall remains. The tower facing E, accessible through an arched entrance facing SE, has - inside - a circular compartment with a niche arranged in axis with the entrance (m 3.7 in diameter), covered in “tholos” (m 5.4 in height). On the left wall, 1.00 m from the floor, there is access to a passage that is now obstructed by the collapse.
In the NE, the wide concave-convex curtain that connects this tower with a third one located further to N. The curtain is built with large polygonal blocks, in the basic rows, and with squared and smaller ashlars in the upper rows. Tower N, cluttered with rubble, shows a short section of the chamber's wall covering on the floor of the collapse. The northern lobe connects to the sub-trapezoidal building with a wide ellipse where a corridor develops. The remaining central tower for a maximum height of m 2.5.
The nearby necropolis overlooks the plateau, with an open view of the lake.
Tomb II has the classic planimetric scheme: an apsidic tomb, a covered funerary corridor, an exedra architectural façade. The grave body is arranged along the SN axis, with an S entrance (m 9 x m 5.53). The external wall, placed on a crepidine in polygonal work, consists of isodome slabs (wall thickness 10.8 m - side panels, m 2.73 - apse). The exedra, with a seat counter interrupted - at the entrance - by a circular platform, consists of rows of isodome stones (maximum rope 11.6 m).
The entrance to the monument, rectangular (m 0.35 x m 0.70; thickness m 0.35), opens into the large central slab of the exedra. The closing door, found not far away, has a parallelepiped shape and rounded corners; a central frame sculpted in relief on one of the major faces allowed it to be adapted to the door. The side and upper faces have cavities to facilitate the movement of the plate. The corridor, rectangular (m 4.7 x m 0.80), is built in isodome work, with vertical blocks at the base and jutting above. A slab and a smaller overlapping block have been preserved on the headboard wall. It is likely that the cover had a truncated warhead. The floor is covered with large slabs.
A trunk-pyramidal 'toothed tann' (width 0.50 m wide), which was found, crowned the top of the exedra.
The tomb dates back to the recent Medium-Bronze Age.
Tomb I is still being excavated and studied.

History of the excavations
The excavations were conducted by Giuseppa Tanda. Tomb II was excavated in 1987, 1988, 1990; Tomb I, the nuraghe and the village are still being excavated.

How to get there
From Abbasanta-Nuoro (SS 131 bis), take the junction for Sedilo/Sud. You go along the town and then, immediately after the sports field, turn left. Continue for about 800 meters, then turn left again. After 400 meters, the road ends in a small space. From here you walk along a stony path bordered by a drywall, always keeping to the left. You come to intersect a larger path, take it to the road, then take the first path on the left. You get to go along the nuraghe which, along the way, is almost always visible in the distance, after about fifteen minutes. The tombs of giants, on the other hand, are located to the left of the path, on the edge of the plateau with a wide view of Lake Omodeo.
