Histria (ancient city)

Histria or Istros (Ancient Greek: Ἰστρίη, Thracian river god, Danube), was founded as a Greek colony or polis (πόλις, city) near the mouth of the Danube (known as Ister in Ancient Greek) on the western coast of the Black Sea. It is near the modern town of Istria. It was the first urban settlement on today's Romanian territory when founded by Milesian settlers in the 7th century BC. It was under Roman rule from the 1st to 3rd centuries AD. Invasions during the 7th century AD rendered it indefensible, and the city was abandoned. In antiquity, it also bore the names Istropolis, Istriopolis, and Histriopolis (Ἰστρόπολις, Ἰστρία πόλις) or simply Istros/Histros (Ἴστρος).

Histriopolis was a fort in the Roman province of Moesia. As Tabula Peutingeriana shows it is situated between Tomis and Ad Stoma; 11 miles from Tomis and 9 miles from Ad Stoma.
