The monument can be found near the marina di Tertenia, in the southern-central part of the region known as Sarrala. The structure stands on a hillock dominating the Foxi ‘e Murdegu beach.
It is a compound-style Nuraghe. The building consists of a main tower, four secondary towers, two courtyards and a cistern well. The structure was built mainly with local rock (porphyry and granite). There are supporting wedges in the external walls made of basalt, a material that is not local and most likely comes from the current-day area of Barisardo. The Nuraghe is also surrounded by an imposing massive wall.
During the excavation work, numerous items were uncovered: fragments of decorative bronze statues, including an archer’s directional flag and the boss of a warrior’s shield. A vase from the Nuragic era was also found with an unusual shape, interpreted as an antique distiller. Lastly, the discovery of some fragments of Mycenaean ceramic is worth mentioning.
The remains of a village were uncovered near the Nuraghe with circular and straight structures, and the remains of cobblestones with rectangular equidistant wells, perhaps housing for the posts of a colonnade.
Take the road out of Tertenia towards Marina di Tertenia. Once past the hamlet of Foxi Murdegu, turn right following the signs for Nuraghe Nastasi. After about 300 metres, leave your car and continue on foot up the hill overlooked by the Nuraghe, following a short pathway.
