This was the first "Hittite" monument discovered in modern times (early 18th century, by the Swede Otter, an emissary of Louis XIV).
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).
