The Giants' Tombs highlights to the Nuraghi Age, were collective
tombs, could contain almost one hundred of bodies, and were
widespread in all the Sardinia.
They were very big and its shape remembers the Bull's Horn which
symbolised the male divinity.
They are composed of a stoned Stele ( a vascular cylinder) also 3 metres high, with a little opening in its bottom which gives to a long corridor, the sepulchral room, covered with charge slab of stone.
At the two sides of the vascular cylinder some big stones draws a half moon.
Next to the corridor the archaeologists have found a lot of  Betili
dedicated to the male and female divinities.
