In the 9th century it was sacked by the Danes and refounded from Abingdon Abbey by King Edgar of England in 964. In the eleventh century the monks engineered the Abbey River as an offshoot of the River Thames to supply power to the abbey's watermill. In late medieval times, the Abbey became famous as the burial place of King Henry VI (whose body was later transferred to St George's Chapel, Windsor). The abbey was dissolved by the commissioners of King Henry VIII in 1537, but the community moved to Bisham.
