The suggestion that the burial place of one of the greatest early Kings of Denmark, Harald Bluetooth, has been identified at Wiejkowo ( In German: Gross Weckow ) in Pomerania - and currently part of the modern Polish state - has attracted some online attention.
Wikipedia has a biography of the King at Harald Bluetooth
An article on warhistoryonline.com sets out the case for Wiejkowo being his burial place and can be viewed at 1,000-Year-Old Burial Site of Legendary Viking King Harald Bluetooth Discovered in Polish Village
The Wikipedia article about Wiejkowo/ Gross Weckow which provides a bit of background can be seen at Wiejkowo and on the same site is a much more detailed account of the Curmsun Disc
King Harald is perhaps most usually associated with the monuments at Jelling in Jutland and Wikipedia has a good account of this major historic site at Jelling stones
