The larger of the two measures roughly 1.2 by 2.6 metres and stands about 2 metres high, with a rectangular opening cut through its centre. That opening, just over a metre tall and less than half a metre wide, may be the remnant of a chimney shaft, though even that identification is uncertain. It is an easy thing to walk past without a second glance, yet these unremarkable fragments are almost certainly what remains of a medieval monastery.

Writing in 1844, a local historian named O'Flanagan described the ruins of a monastery as still traceable within the deer-park of Castlecor House, a landscaped demesne of the kind common to the Anglo-Irish gentry, where earlier structures were often absorbed into ornamental grounds or simply left to the grass. A later account, from 1934, identified the monastery as Augustinian, a widespread mendicant order that established numerous houses across medieval Ireland. Scholars Gwynn and Hadcock, however, were less certain, classifying it as unclassified and noting that its earliest documentary trace is a mention in a plea roll from the late thirteenth century. Plea rolls were records of legal proceedings in medieval courts, and the appearance of an abbey in such a document suggests it was a functioning institution with property interests at that time, even if its precise affiliation and full history remain unclear. A photograph taken sometime between 1905 and 1925 by the Cork antiquarian Grove White captured the masonry as it then stood, providing a rare visual anchor for a site that has otherwise slipped almost entirely from the record.
