Monasternagalliaghduff

[4]: 42 [2] One of the earliest recorded nunneries in Ireland,[5] it is first mentioned in 1298, and was founded on land donated by John FitzThomas of Connello (who died in 1261).

[4]: 43 fn.3  While there are few details, it appears in court and land records over the succeeding centuries, and at Dissolution of the Monasteries during the Reformation in Ireland, in 1541, a valuation is given.

[4]: 48–50 Remains include the abbey church to the east of the cloister, with two small spaces adjacent - one of which is now known as the Black Hag's Cell but which appears to have been a sacristy - a refectory to the south,[2] and a vaulted building to the west.

The church and cloister walls were assessed as being of similar age, and their windows dated to the 13th century.

[4]: 55–59 Burials were also located, and the church plate was reportedly found in the late eighteenth century.
