Cuthbert was a saint of the early Northumbrian church in the Celtic tradition. He was a monk, bishop and hermit, associated with the monasteries of Melrose and Lindisfarne in the Kingdom of Northumbria, today in north-eastern England and south-eastern Scotland. Both during his life and after his death, he became a popular medieval saint of Northern England, with a cult centred on his tomb at Durham Cathedral. Cuthbert is regarded as the patron saint of Northumbria. His feast days are 20 March and 4 September.
