Histria or Istros , was a Greek colony or polis near the mouths of the Danube, 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. Scymnus of Chios (ca 110 BC), dated its founding to 630 BC, while Eusebius of Caesarea set it during the time of the 33rd Olympic Games (657 – 656 BC).
