The main tower and a secondary tower of Nuraghe Oes contain a single room, which was once divided into three spaces with wooden garrets supported by recesses, attached thanks to holes made in the walls.
Dating back to a period between the Bronze Age and the Iron Age (9th-6th century BC), the Oes is a majestic work of Nuragic architecture, built using well-finished basalt rocks. The main building consists of a tower (keep) with three floors and a truncated cone shape that ‘falls’ on all sides with a uniform slope. It is made up of 29 rows of stones. It is 16 metres tall and has a diameter of 11 and a half metres, making it the largest Nuragic building found so far. It once had a tholos vault (false dome). Against it, there is a bilobed bastion, with a perimeter of 50 metres, on two levels and with two entrances, that encloses a courtyard and two secondary towers. One of these is well-preserved. The overall complex measures 425 square metres and also includes a sacred area, with a fence (temenos) that has a vaguely hexagonal shape and a little megaron temple, the remains of a Tomb of Giants, of which you will notice the stele resting on the ground, a vast residential settlement of circular and oval huts. Their type is uncertain (perhaps cisterns and a second little temple). Between the sacred area and the Nuraghe, twenty rocks laid on edge and fixed in the ground resemble a megalithic circle.
