Santorini
Santorini also known as Thera is a volcanic island located in the southern Aegean Sea, about 200 km (120 mi) southeast from Greece's mainland. It is the largest island of a small, circular archipelago which bears the same name. It forms the southernmost member of the Cyclades group of islands. It is composed of the Municipality of Thira and the Community of Oía .Santorini is essentially what remains of an enormous volcanic explosion, destroying the earliest settlements on what was formerly a single island, and leading to the creation of the current geological caldera.
The name Santorini was given to it by the Latin Empire in the thirteenth century, and is a reference to Saint Irene. Before then it was known as Kallístē ( "the most beautiful one"), Strongýlē ( "the circular one"), or Thēra. The name Thera was revived in the nineteenth century as the official name of the island and its main city, but the colloquial name Santorini is still in popular use. There is also compelling evidence that has led archaeologists to believe that Thera is the lost island of Atlantis.
