Akrotiri (Santorini), ancient Thera by Nikolaos Oikonomou

Santorini's prehistoric city

Akrotiri is the name of an excavation site of a Minoan Bronze Age settlement on the Greek island of Santorini, associated with the Minoan civilization due to inscriptions in Linear A, and close similarities in artifact and fresco styles.[1] The excavation is named for a modern Greek village situated on a hill nearby. The name of the site in antiquity is unknown.
Akrotiri was buried by the widespread Theran eruption in the middle of the second millennium BC[2] (during the Late Minoan IA period); as a result, like the Roman ruins of Pompeii after it, it is remarkably well-preserved. Frescoes,[3] pottery, furniture, advanced drainage systems and three-story buildings have been discovered at the site,[4] whose excavation was started in 1967 by Spyridon Marinatos.
Certain historians hold this settlement, as well as the disaster that left it unknown to most of history, as the inspiration behind Plato's story of Atlantis, as mentioned in his dialogues Timaeus and Critias. Excavated artifacts have been installed in a museum distant from the site (Museum of Prehistoric Thera), with many objects and artworks presented. Only a single gold object has been found, hidden beneath flooring, and no uninterred human skeletal remains have been found. This indicates that an orderly evacuation was performed with little or no loss of life.

Excavation
An ambitious modern roof structure, meant to protect the site, collapsed just prior to its completion in 2005, killing one visitor.[5] No damages were recorded to the antiquities.[6] As a result of this, the site was closed to visitors until April 2012, when it was once again opened to the public
