13 photos showing one of the world's most spectacular islands. Located on a steep coast, 300 m above sea level, villages, that are partly built into the rock, present a stunning view towards the caldera. The whole island was formed by a gigantic volcanic eruption 3,600 years ago. A miraculous place not only for photographers.
