Near the hamlet of Pratobello, about 15 kilometres from Fonni, the ‘highest’ village of the island, a Nuragic necropolis with four similar Tombs of Giants arises, standing on a plateau in the midst of the splendid Riu Madau valley, at the foot of the Corr’e Boi passage, so-called because it looks like the head of a gigantic bull. The tombs, dating back to the early or late Bronze Age and perhaps connected to the nearby Nuragic village of Gremanu, are structured around an amphitheatre and face the rising sun. Two of them are well-preserved, having been excavated and studied between 1982 and 1986 by the ‘father’ of Sardinian archaeologists, Giovanni Lilliu.
