Heraclea Pontica"Heraclea Pontica (/ˌhɛrəˈkliːə ˈpɒntɪkə/; Greek: Ἡράκλεια Ποντική, romanized: Hērakleia Pontikē), known in Byzantine and later times as Pontoheraclea (Greek: Ποντοηράκλεια, romanized: Pontohērakleia), was an ancient city on the coast of Bithynia in Asia Minor, at the mouth of the river Lycus. It was founded by the Greek city-state of Megara in approximately 560–558 and was named after Heracles whom the Greeks believed entered the underworld at a cave on the adjoining Archerusian promontory (Cape Baba). The site is now the location of the modern city Karadeniz Ereğli, in the Zonguldak Province of Turkey." - (en.wikipedia.org 22.09.2020) Turkey
