A great and ancient tradition takes place on Saint Patrick's Holy Mountain in Mayo, Croagh Patrick, next Sunday, the last Sunday in July, known as Reek Sunday. Pilgrims, many in their bare feet, will be climbing from early morning. Indeed, the mountain and many of the traditions probably date back even before Saint Patrick and Christianity. Archbishop Neary will be celebrating Mass, in the chapel on the summit, at 11 a.m and this will be broadcast live on RTE 1.
