Elafonisos is a small island off the southeastern coast of the Peloponnese in Laconia, famous today for its turquoise waters and the spectacular Simos Beach.
A massive earthquake and tsunami dramatically reshaped the coastline, sinking Pavlopetri and separating Elafonisos from the mainland, giving it the island form we know today.
Pavlopetri is located just off the coast of southern Laconia in the Peloponnese, Greece, between Pounta (Punta) Beach on the mainland and the island of Elafonisos.
Pavlopetri dates back to around 3000 BC, making it the oldest known submerged city in the world.
