Santorini is an island in the southern Aegean Sea. This beautiful island is essentially what remains after an enormous volcanic eruption that destroyed the earliest settlements on a formerly single island, and created the current geological caldera and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, through a gigantic tsunami. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis. The major settlements include Fira (Phira), Oia, Kamari, Perissa, Imerovigli, Pyrgos, and Therasia. During our visit you have the opportunity to see nearly all of them.
