Danube Delta in Romania The Danube Delta is perhaps the least inhabited region of temperate Europe. In the Romanian side live about people, of which in the port of Sulina, which gives an average density of approx. 2 inhabitants per km².
The Danube Delta is a vast area on the western coast of the Black Sea. This was possibly one of the escape routes taken by Medea, Jason and the Argonauts in their flight from Aeëtes' forces having stolen the Golden Fleece.
