It might have been called ‘Hy Brazil the Isle of the Blessed’, for a blessed isle it unquestionably is. There is a reverence in the air here that is almost palpable. It has been generated by the prayers and sufferings of the pilgrims that have trod its rocky surface for fifteen hundred years. But the resemblance to Hy Brazil must end there. Hy Brazil was a mythical place, Lough Derg is a reality. It is one of the oldest places of pilgrimage in Christendom, and secure in that knowledge it reposes quietly and unobtrusively in the brown lake amongst the little bare hills. It has no need to advertise itself, for it is famous throughout the Christian world. To this hallowed spot year after year and century after century the faithful have flocked barefooted and penitent to lift up their hearts in prayer to God.
