Cong Abbey is a historic site located at Cong, on the borders of counties Galway and Mayo, in Ireland's province of Connacht. Founded in the early 7th century, by Saint Feichin, the abbey was destroyed by fire in the early 12th century. Turlough Mor O’Connor, the High King of Ireland, refounded the abbey circa 1135. His son Rory O'Connor, the last High King of Ireland before the Norman invasion, constructed new buildings and also lived the last 15 years of his life at the abbey, dying in 1198. The monastery adopted the Augustinian rule some years later.
