The Greek City That Vanished Overnight

An entire ancient Greek city vanished in a single night. No survivors. No ruins left standing. Only silence beneath the sea. In 373 BCE, Helike was one of the most powerful cities along the Gulf of Corinth—wealthy, influential, and devoted to Poseidon, god of the sea and earthquakes. Then, without warning, the earth began to shake. The sea pulled back. And within minutes, Helike was erased. Ancient writers claimed its streets lay beneath the water, frozen in time. Others believed the city had been swallowed whole by the earth itself. For over two thousand years, Helike remained a mystery—searched for, debated, and compared to the legend of Atlantis. This documentary explores what really happened to Helike, why it disappeared so completely, and how modern archaeology finally uncovered the truth beneath layers of mud, water, and time.
