Ancient wooden Br. — Lough Derg

It is traditionally believed that a monastic settlement was founded here in the fifth century by St. Patrick who installed Dabheoc as the first abbot. There are forty-six islands in Lough Derg but only two of them are of archaeological interest. The original monastic settlement is believed to have been located on Saint's (formerly St. Dabheog's) Island. This became a priory dependant on the Augustinian Abbey of SS Peter and Paul, Armagh in the 1130's and was suppressed and abandoned towards the end of the sixteenth century. The chief concern of the monastery was to minister to the needs of the pilgrimages to the cave, known as St. Patrick's Purgatory, on nearby Station Island. Some sources suggest that the original cave had been located on Saint's Island and that the pilgrimage was later transferred to its present location (Leslie 1961, 9-10). The Lough Derg pilgrimage was famous throughout Europe in the middle ages and a large literature grew up around it (Curtayne 1962, 160-62). An ancient roadway to the pilgrimage site from the village of Pettigo passes Rathnacross ringfort (DG105-002-) and Templecarn old church and burial ground (DG105-003; DG105-015-). The roadway continues to a point on the SW shore of the lake where a wooden bridge (DG101-002-) connected it to Saint's Island. Natural boulders projecting from the lake may be the remains of the supports for this bridge. On the SE shore of the lake is a natural L-shaped stone known as St. Brigid's Chair. St. Dabheoc's Seat on top of a hill to the S of the lake formerly consisted of a stone seat in front of a 'grave-like opening' (O'Connor 1879, 40).
