The volcano is an active volcano that has erupted many times in history, the most recent of which was in 1956, when it nearly destroyed most of the buildings in Fira and Oia. But it is not just a disaster. The violent eruption in 1500 BC caused the entire center of Santorini to fall, forming the crescent-shaped landscape and magnificent cliff landscape. The best view of the Santorini crater is here. If you want to see it closer to the crater, you can also take a small submarine to the deep waters under the crater to visit.
