Ælfheah, more commonly known today as Alphege, was an Anglo-Saxon Bishop of Winchester, later Archbishop of Canterbury. He became an anchorite before being elected abbot of Bath Abbey. His reputation for piety and sanctity led to his promotion to the episcopate and, eventually, to his becoming archbishop. Ælfheah furthered the cult of Dunstan and also encouraged learning. He was captured by Viking raiders in 1011 during the siege of Canterbury and killed by them the following year after refusing to allow himself to be ransomed. Ælfheah was canonised as a saint in 1078. Thomas Becket, a later Archbishop of Canterbury, prayed to Ælfheah just before his murder in Canterbury Cathedral in 1170.

The Old Minster was the Anglo-Saxon cathedral for the English diocese of Wessex and then Winchester from 660 to 1093. It stood on a site immediately north of and partially beneath its successor, Winchester Cathedral.
