From Wikipedia, the free encyclopedia.
Jomsborg was a legendary viking settlement in Pomerania by the Baltic Sea. It's generally disputed whether such a settlement existed at all, all of the proofs are coming from later era and from distant Iceland. Contemporary sources mention rather a city known as Julin, Jumne or Wolin, which supposedly was known for Slavic pirates, where also Danes and other Scandinavians could easily find refuge.
Harold Bluetooth had to take refuge from his son here in the late 900s.
