Most of the wells and springs in Ireland that were venerated by the Celts, were taken over by the Church and became Holy Wells. One such is St. Kieran’s, just outside the village of Carna. It’s a sad wet place, ferns dripping and brambles ready to snag the unwary. But up here is a cross to St. Kieran. He is supposed to have stayed here on his way to the Aran Islands to convert the heathen. The water from his well is supposed to cure problems with the sight.
