Sardinia, a tiny Mediterranean island barely the size of Hawaii hides the remains of an ancient civilization that appeared here almost 4,000 years ago.

While Pharaohs of Egypt were building their last pyramids this powerful new civilization was inventing fortress-like towers known as nuraghe, religious sanctuaries and extraordinary geometrically shaped tombs. Who were the Nuraghic people who built these monuments?

In the last five years a team of international archaeologists and scientists has been studying the ruins as never before helping to unlock the secrets of one of the most remarkable Bronze Age cultures the Mediterranean has ever known.
