The wide range of building types found in the complex of S’Ortali ’e su Monte, in the countryside of Tortolì, bears witness to the very long human presence in the area: they include a nuraghe with two rings of walls, a village, a giants’ grave, three menhirs and an underground tomb.
The nuraghe has an entrance with a small opening above the lintel, a staircase leading to the upper floors with corbelled ceiling and a chamber with three niches set in a cross shape. Its interior has revealed a store with 19 bronze axes and the remains of some burials dating back to medieval times.
The giants’ tomb is of the upright-stone type, with a rounded central stele, today broken off and laying on the ground. It still shows part of the apse-shaped burial chamber facing east, constructed in granite and porphyry blocks of medium size. The tomb chamber, rectangular in shape, is framed by stone slabs set vertically (orthostats) topped by courses of roughly shaped blocks. The floor consists of the rocky outcrop. The three granite menhirs are of different types: the first – unshaped, pointed and broken into two pieces – is set on the ground; the other two, shaped in proto-human form, are ogee-shaped with flat-convex section.
