The island of Santorini has a pretty explosive past. It’s perched over the remains of a much larger land mass that sank almost 4,000 years ago when a volcano blew its top, leaving the blue caldera and steep cliffs behind.
It is these cliffs and the flooded caldera that have become Santorini’s iconic calling card, and the first stop on your Santorini tour. Here’s your first bit of trivia: The whitewashed homes that appear on so many postcards and photographs are larger than they appear on the outside. They’re partially built into existing cliffside caves, and feature some of the most distinctive Mediterranean architecture you’ll ever see.
