Saint Cuthbert (c. 634 – 20 March 687) was an Anglo-Saxon monk, bishop and hermit associated with the monasteries of Melrose and Lindisfarne in the Kingdom of Northumbria, at that time including, in modern terms, northern England as well as south-eastern Scotland as far north as the Firth of Forth. Afterwards he became one of the most important medieval saints of England, his cult being centred at Durham Cathedral. Cuthbert is regarded as the patron saint of northern England. His feast day is 20 March.
