Cholsey Abbey
Cholsey Abbey was an Anglo-Saxon abbey in Cholsey in what is now the English county of Oxfordshire, which was founded in the mid-990s by King Æthelred the Unready on land which he had acquired from his mother, Ælfthryth. It was dedicated to Æthelred's half-brother, Edward the Martyr, and its first abbot was Germanus. It may have been sacked by the Vikings in 1006, and by the time of the Norman Conquest in 1066 it had disappeared.
