Monasternagalliaghduff (Mainistir na gCailleach Dubh;Irish for "Black Nuns' Abbey"), also called the Abbey of St Catherine de O'Conyl or simply Old Abbey, is a ruined Augustinian abbey in County Limerick in Ireland. The abbey lies in a small valley about two miles east of the village of Shanagolden, in the townland of Oldabbey (named after it) in the civil parish of Robertstown, and barony of Shanid (formerly part of the barony of Connello or O'Conyl).
One of the earliest recorded nunneries in Ireland, it is first mentioned in 1298, and was founded on land donated by John FitzThomas of Connello (who died in 1261). It was dissolved in 1541 at the Dissolution of the Monasteries during the Reformation in Ireland.
Some legends relate to the Abbey:
Remains include the abbey church to the east of the cloister and refectory to the south. Modifications to the church in the 15th Century saw the inclusion of an east window in the church as well as a doorway in the north.
