Perdas Marmuradas, in the conical stones is represented the fertility

In the road that connects Macomer to Santu Lussurgiu, on Sant’Antonio Mount, Tamuli locality, it is possible to visit three Tombe dei giganti (Giants’ graves). Interesting are also “sas Perdas Marmuradas”, conical stones slightly shorter than two meters: some of those have some protuberances that represent the women' s breasts, therefore the Goddess Mother who symbolizes the fertility.

Again in Marghine-Planargia region, not far from Tinnura, there is the giants’ grave of Su Crastu Covaccadu.

Nearby Bìrori there are two very similar with each other giants' tombs, those of Palattu and Lassìa.
