The island of Santorini, is also known as Thira or Thera.  The Thira is named for Santorini, the world-famous volcanic island located in the most southern part of the Cyclades group of islands in the Aegean Sea, in Greece. Great poets have sung its praises, a 4,000 year old history. Shades of red create unreal sunsets, the caldera offers dramatic sea views and the enormous cliffs are dotted with dreamy Cycladic white washed houses.
