Gwyddfarch was a hermit and founder of a Celtic abbey at Meifod in Wales.
[1] He was a son of Amalarus[2] and disciple of Saint Llywelyn at Welshpool.
This establishment became the mother church of several other monasteries and was a centre of the order for over one thousand years, and within a generation the monastery had become a centre of pilgrimage.
Gwyddfarch taught Tysilio,[4] who replaced him as abbot.
[5][6] Legend holds that near the end of his life Tysilio talked the aging abbot out of a pilgrimage to Rome.
