According to tradition St Ronan and his daughter St Lasair established a church here on the banks of Lough Meelagh in the 6th century. The present church ruin, which dates from the 14th century, was built by the O’Duignan family. On the northern side of the church is a crypt belonging to the McDermott Roe family.
This is where Turlough O’Carolan, the last of the Irish Bards, is buried.
The Abbey was used by monks, one of whom is buried within the ruins. Details of his death are carved on a large flagstone which is still inside the Abbey wall
