A causewayed enclosure discovered in 2003 at Maugheraboy is one of the earliest indications of Neolithic farming activity on the Cúil Irra peninsula. The nearby megalithic cemetery of Carrowmore forms part of a huge complex of Stone Age remains connecting Carrowkeel in south Sligo to the Ox Mountains, to the Cuil Irra Peninsula, where the passage tomb named after the legendary Queen Maeve, Miosgán Médhbh, dominates the western skyline from the crest of Knocknarea Mountain.
