According to fanciful theories and popular beliefs, they were the tombs of Cyclopean peoples, ancient inhabitants of Sardinia of whom no trace remains. Instead, it is the evolution of covered gallery tombs (or alleè couverte) starting in the Early Bronze Age (around 1800 BC). They are generally found in the area around nuraghi and villages and have often revealed fundamental artefacts for the study of the Nuragic age. They were probably a place of mysterious rituals and some still believe that the stones with which they were built release a mysterious energy.
The route starts inside an evocative forest in Ogliastra and heads north alongside splendid water landscapes, ending on the slopes of Gennargentu.
