About
About Heraclea Pontica – Megarian Mole of Karadeniz Ereğli
560 BCE Megarian colony at mouth of Lycus (Kelpe) founding Heracles' descent cave (Acheron). Tyranny 364 BCE Clearchus + mercenary harbour; 281 BCE Lysimachus and later Mithridates VI base; 72 BCE Roman siege of Triarius. Doric ashlar mole 220 m at –1 to –4 m arcs from promontory under modern Ereğli coal pier, mapped by Turkish Geological Institute 1999 side-scan. Cave sanctuary and Achilles tomb hill above. Continuity to Ottoman Ereğli coaling station.
