Akrotiri was a Cycladic Bronze Age settlement on the volcanic Greek island of Santorini.
The settlement was destroyed in the Theran eruption sometime in the 16th century BC and buried in volcanic ash, which preserved the remains of fine frescoes and many objects and artworks. The settlement has been suggested as a possible inspiration for Plato's story of Atlantis. Akrotiri has been excavated since 1967.
