Anglo-Saxon abbey Ely Abbey was founded in 672, by Æthelthryth (St Etheldreda), daughter of the East Anglian King Anna. It was a mixed community of men and women.[3] Later accounts suggest her three successor abbesses were also members of the East Anglian Royal family. In later centuries the depredations of Viking raids may have resulted in its destruction, or at least the loss of all records.[4] It is possible that some monks provided a continuity through to its refoundation in 970, under a Benedictine rule.[4] The precise siting of Æthelthryth's original monastery is not known. The presence of her relics, bolstered by the growing body of literature on her life and miracles, was a major driving force in the success of the refounded abbey. The church building of 970 was within or near the nave of the present building, and was progressively demolished from 1102 alongside the construction of the Norman church.[5] Ermenilda of Ely was an Abbess here, as well, after her husband Wulfhere of Mercia died in 675.
