Akrotiri is a Minoan Bronze Age settlement on the island. The settlement was destroyed in the Theran eruption about 1627 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. The site has been excavated since 1967.
Guided tours are also available in the Archaeological site.
