The Cathedral Church of St Peter, St Paul and St Andrew has its roots in Anglo-Saxon times. The first abbey was established at Peterborough (originally called Medeshamstede) in 655 AD and largely destroyed by Viking raiders in 870. In the mid 10th century a Benedictine Abbey was created from what remained. Some buildings were destroyed in Hereward the Wake's resistance to the Norman Conquest in 1069, but the church survived until an accidental fire swept through it in 1116. The present building was begun in 1118, consecrated in 1238 and the structure of the building remains essentially as it was on completion. Most significantly the original wooden ceiling survives in the nave, the only one of its type in this country and one of only four wooden ceilings of this period surviving in the whole of Europe, having been completed between 1230 and 1250. There is some fine 16th century fan vaulting at the east end of the church. Peterborough grew to be a wealthy monastic house, with 120 monks just before it was dissolved in 1539. However, the abbey church survived as Peterborough Cathedral. Parliamentary troops caused damage to glass and monuments during the Civil War. Two queens were buried in the Cathedral, Katherine of Aragon and Mary Queen of Scots: however, in 1612, James I/VI had his mother re-buried in Westminster and her grave is now empty.
