Winchester Cathedral Priory was a cathedral monastery attached to Winchester Cathedral, providing the clergy for the church. Cenwealh son of Cynegils is credited with constructing the Old Minster of Winchester in the 640s, and a new bishopric was created in the 660s with Wine as the first bishop. Although attacked by the Vikings in 860 and 879, the monastery survived and recovered. The priory controlled the Sister Hospital at Winchester, and maintained a school.
