Helike

Helike was an ancient Greek city in Achaea on the north shore of the Gulf of Corinth that was destroyed and submerged following an earthquake and accompanying sea disturbance in 373 BCE. Its disappearance became a subject of classical accounts and long-standing historical interest.

Archaeological investigations and survey work in the coastal plain near the modern village of Elliki have identified buried and waterlogged remains consistent with a submerged settlement and harbor deposits. Finds have helped to match the archaeological evidence with ancient descriptions of the city and its abrupt end.

Ancient Helike functioned as a Greek city-state until its destruction in 373 BCE, after which the site was abandoned and became associated with legend. Interest in locating the city’s remains prompted recurrent archaeological campaigns from the late 19th century and especially in the late 20th and early 21st centuries.

The site lies on the northern coast of the Gulf of Corinth in Western Greece, close to the modern town of Aigio and the village known today as Elliki, in a low-lying coastal plain where ancient harbor features have been investigated.

• Catastrophic sinking: The city's sudden destruction in 373 BCE by earthquake and tsunami was recorded by ancient authors and made Helike a topic of historical and archaeological interest.
