About
About Olous (Olus) – Sunken Dorian City
Powerful Dorian harbour city of ancient Crete (one of 147 city-states), rival of Lato and Hierapytna, controlling Elounda Bay. Merged with isthmus causeway to Kolokytha/Spinalonga peninsula; subsided by 2nd century CE earthquake (c. 150 CE) leaving basilica floors, wall footings and quay blocks in 0.5–3 m water straddling modern Elounda–Spinalonga causeway. Shallow Offshore ERT survey 2016 mapped submerged grid. Best snorkeled on calm mornings; visible walls on both sides of causeway.
Why it mattersOnly Cretan Dorian harbour preserved in shallow water; demonstrates Late Roman seismic subsidence of eastern Crete coastline.
