Marmara Ereğlisi (Turkish: [ˈmaɾmaɾa æɾeːlisi]; Greek: Ηράκλεια), also spelled Marmaraereğlisi, is a municipality and district of Tekirdağ Province, Turkey. Its area is 175 km2, and its population is 29,549 (2022).
Facts
Ereğli is 30 km east of the town of Tekirdağ, and 90 km west of Istanbul near a small pointed headland on the north shore of the Marmara Sea. It is called Marmara Ereğlisi (or Marmara Ereğli in colloquial usage) to distinguish it from the two other large towns in Turkey with the name Ereğli (deriving from the Greek name Heraclea), one in Konya Province (Konya Ereğlisi), the other on the Black Sea coast (Karadeniz Ereğli).
History
The town, originally a Samian colony, was founded as Perinthos (Greek: Πέρινθος), in English usually known by its Latinized form as Perinthus. In about 300 AD, it was given the name of Heraclea (Ἡράκλεια). It was built amphitheatre-like on the hillside of a cape extending into the Sea of Marmara, close to where the modern town stands. Its port and its position at the junction of several sea-routes, made it a town of commercial importance. It became famous because of its resistance to Philip II of Macedon in 340 BC. Many of its coins have survived, and identify the festivals held there.
At an early date, according to tradition in the Apostolic Age, Heraclea became a Christian bishopric.
