Histria or Istros (Ancient Greek: Ἰστρίη, Thracian river god, Danube), was a Greek colony or polis (πόλις, city) near the mouths of the Danube (known as Ister in Ancient Greek), on the western coast of the Black Sea. Established by Milesian settlers in order to facilitate trade with the native Getae, it is considered the oldest urban settlement on Romanian territory.
