As part of a broader program of integrated enhancement of inland areas, the stratified excavation in the archaeological area of Cuccuru Cresi Arta was carried out in 2004.
Faint traces of wall remains from the historic period have been found on the hilltop.
A quadrangular structure, built of medium-sized stones, has emerged, set on the rocky bank below. It is possible that it is to be referred to a cult building (given the toponym and the presence of a cross), but certainly, given the strategic location, the structure dominated the fertile surrounding land and thus also performed a function of control over the territory.
The most significant feature of the excavation is the discovery of a Nuragic structure, elliptical in plan, set at the edge of the ridge on the southwest side.
The structure was dug more than two meters into the rock plateau and lined, as far as it was exposed, with twelve rows of stones.
The various fill layers have returned exclusively Nuragic pottery and tools, the oldest of which are attributed to Middle Bronze.
The most plausible hypothesis is that it is the combustion chamber of a kiln, used for firing pots.
Bone samples, taken from US 36, which was among the deepest layers, were dated at C14 between 1520 and 1300 B.C. date calibrated at 68% probability (at 95.4% probability there is a range between 1620 and 1130 B.C.).
