Sardinia has an age-old story, told by the archaeological evidence dotted throughout the territory. The tangible signs of the prehistoric island are endless: menhir, dolmen, domus de Janas, sacred wells, tombs of the giants and countless Nuraghe complexes. Enormous stones that have been guarding secrets for four thousand years. Buildings, often intact, of the first civilizations ever to exist in Europe, the only sites of their kind in the world, a patrimony to be discovered and experienced: this is the Stonehenge of the Mediterranean.
