St David – Patron Saint of Wales Biography and Key Facts

St David, known in Welsh as Dewi Sant, is the patron saint of Wales and a central figure in the early Welsh Church. The broad historical outline is clear—he was a 6th-century preacher, monk, and bishop associated with south-west Wales—but many details of his life come from later tradition rather than fully secure contemporary records.

According to Wales.com, his cult became established well after his death, and he has been recognised as the patron saint of Wales since the 12th century. Over 60 medieval parish churches in Wales were eventually dedicated to him, a sign of how widespread his veneration became. His feast day, 1 March, commemorates the date of his death and has grown into a celebration of Welsh identity both in Wales and among Welsh communities abroad.

Traditions preserved at St Davids Cathedral include his remembered last words: “Be joyful, keep the faith, do the little things you have seen me do.” That phrase, gwneud y pethau bychain in Welsh, remains a popular motto in Wales today.
