To discover the meanings of this word , we need go back in time, was the 1450 BC when the catastrophic eruption of the volcanocovered all island under the lava.
The greater central part of the island, about 80 sq. km, collapsed to the bottom of the sea and the waves rushed in to cover it forming a gigantic basin which is now called Caldera.In Caldera, 400 meters deep, still exists a gigantic crater of 10 kms wide. In the middle of the Caldera there is a new volcano & the hot springs were you can swim (Nea & Palia kameni ).
