On a Greek Island, Clues to a Mysterious Civilization

In the jewel-bright Aegean Sea, a small Greek island holds an ancient mystery. 4,000 years ago, Dhaskalio was a promontory connected to its larger neighbour, the island of Keros. On this pyramid-shaped hill stood a sanctuary where visitors brought intentionally broken statues.

A complex of buildings and terraces grew built with many tons of marble quarried on another island. Water conduits ran through the complex, advanced engineering for the age. In the 3rd millennium BC, Keros was becoming one of the Greece's first urban centers. But what made the sanctuary sacred in the first place is yet to be discovered.
