St. Machan is the patron saint of Sodor.
During the sixth century, missionaries from the "Iona School" arrived on Sodor and settled in the more densely-populated south. St. Machan, however, settled in a cave near Culdee Fell, in the north. That cave has since become a place of pilgrimage. People came from far and wide to be baptised in Loey Machan, named in his honor.
