Santorini, or Thera island has a long illustrious history. It's strategic location in the southern center of the Aegean sea made it the cultured hub of prehistoric Greece. The island was most active during the Bronze Age, and remained relevant all the way into Hellenistic and Roma era.

All the spectacular villages you see clinging precariously at the edge of the cliff are built at the rim of the volcano's mouth. The sea you see below is the sea that filled the enormous crater after the volcano subsided it's activity. Thera volcano is still active and the most visible manifestation is the tiny island in the center of the volcano that is slowly growing through the constant volcanic activity.
