Haegelisdun was the site where Edmund the Martyr the King of East Anglia was killed by the Viking Great Heathen Army, and were the initial place where his relics were venerated before moving to Beodricesworth monastery (modern day Bury St Edmunds).
St Edmund's incorrupt [1] relics had been venerated [2] from around the early tenth century at in a wooden chapel in Haegelisdun commemorating the original burial place near to where he was killed.
The location has never been conclusively identified. [3] The placename was long and widely thought - probably in error [4] [5] - to refer to Hoxne in Suffolk. [6] Other proposed sites have been Bradfield St Clare, Hellesdon in Norfolk (documented as Hægelisdun c. 985) and more recently Maldon in Essex. [7] [8] [5]
At a date generally assumed by historians to have been during the reign of Æthelstan, who became king of the Anglo-Saxons in 924, Edmund's body was translated from Haegelisdun to Beodricesworth monastery. [9] [10]
