Jomsborg or Jomsberg was a Viking settlement in territory on the Baltic coast, inhabited by an order of Scandinavian mercenaries known as the Jomsvikings. It was originally the home of Slavic-speaking pirates, but where Danes and other Scandinavians could also easily find refuge. Vineta was supposed to have been a most glorious city, which vanished. However no traces have ever been found. The territory surrounding Jomsborg was conquered by the disinherited Swedish prince Styrbjörn Starke who later gave it to the Danish king Harald Bluetooth, who had to take refuge from his son there.
