Take a tour of Santorini in Greece -- part of the World's Greatest Attractions series by GeoBeats. Hi, I am Naomi and I am very excited to show you the world's greatest attractions. Cut into harsh cliffs, Santorini boldy faces the shining Aegean Sea. Classic white-washed buildings give the island a dazzling feel. Santorini sits perched atop a volcanic crater, now a lagoon. Watching ships come off the sea brings memories of celebrated Greek epics.
