The Oes nuraghe is located in the center of the Campu Giavesu plain near the course of the Mannu river, in Meilogu-Logudoro, within the Nuraghi valley, in the north-west of Sardinia.
The nuraghe is known above all for the unusual construction characteristics of the main tower, which contains a single “tholos” chamber divided into three rooms by wooden floors supported by risaws and holes carved in the wall structures.
It is part of a vast settlement that includes an antemural equipped with towers, a sacred area - with 'temenos' and a megaron temple - and, all around, a vast settlement.
The monument consists of a main tower, which is supported by a two-level bilobed bastion that encloses two secondary towers and a courtyard.
The main circular tower (diam. m 16.15; height 11.40 m) is accessed through the window on the first floor, accessible by climbing the curtain wall of the bastion and the filling of the courtyard.
The opening, trapezoidal (width m 0.80; height m 2) and with an exhaust window, appears decentralized towards S. The window illuminates the trumped and flat back door, which in the middle of the development is intersected by the spiral staircase that leads to the floors above. The path of the connecting compartment is illuminated by loopholes and small cabinets to contain lights. A further peculiarity of the staircase is represented by the presence of a nich-closet.
The room on the first floor - central, not perfectly circular (diam. m 3.75-4.30) and apparently devoid of subsidiary spaces - appears today almost completely filled with boulders and earth.
The environmental cover system consists of a saw (depth 25-50 cm) on which six faced holes are made, similar in shape and size.
Walking along the spiral staircase, you reach the entrance that enters the environment of the second floor, elliptical (diam. m 5-4.50; height 3.30 m) and widely soaring.
The bastion (m 25 x 12.5; height m 6) was accessed through two entrances arranged respectively in the SE and NE curtains.
The main entrance, built in the center of the SE curtain, leads into a corridor with a trap-drain and a niche that leads to a narrow passage that is now inaccessible.
The second entrance to the bastion, open on the NE side, leads to a long corridor now obstructed by the collapse, equipped with a trap-drain and a niche.
Very little can be read about the secondary tower. Conversely, the other tower is better preserved, whose entrance was originally supposed to open onto the SE wall of the courtyard. Of this part of the added body, we can see in part the chambers of the two levels, almost completely filled with collapse. These rooms were also separated by a floor resting on a chain and in three large quadrangular openings functional to the insertion of support beams.
The upper floor room could be reached through a short straight corridor open on the N side.

History of studies
The nuraghe has been mentioned since the nineteenth century.

How to get
There From the Torralba railway station (reachable from the SS 131 - junction for Torralba at km 173.2), you walk parallel to the railway line, for about 700 meters, until you reach the nuraghe clearly visible from afar.
