It is easy to overlook, and by 2015 satellite imagery showed it consumed by heavy vegetation. Yet this modest feature may carry a history stretching back to the medieval church itself, making it one of the quieter puzzles in a landscape that rewards patient attention.

The pond lies immediately east of a structure recorded as the Summer House, and close to the Augustinian nunnery known as Monasternagalliaghduff, a foundation whose name refers to the dark or black nuns of the Augustinian order. The 1840 Ordnance Survey six-inch map records the pond as a clearly defined rectangular feature at the southern end of the formal garden of Old Abbey House, near what are noted as the cellars. The antiquarian T. J. Westropp, writing in 1904, described it as shadowed by fine yews and lime trees and extending along the foot of the garden, and he raised the possibility that it dated from monastic times. Monastic fish-ponds, known as vivaria, were a practical feature of medieval religious houses across Ireland and Britain; communities relied on them to maintain a supply of fresh fish, particularly important during the many fasting days of the church calendar. Whether this particular pond served the nunnery in that capacity has never been confirmed, but the proximity is suggestive.

The site sits in pasture and the surrounding area was heavily overgrown as of the most recent available imagery. There is no formal public access recorded, and the pond itself is not a managed heritage feature, so anyone wishing to locate it should treat it as a field observation rather than a visitor destination. It sits approximately forty metres west of the nunnery remains and can be cross-referenced against the 1840 OS six-inch mapping, where it appears at the southern edge of the Old Abbey House garden. The yews and lime trees Westropp admired may or may not survive, but the outline of the pond, if visible at all through the overgrowth, still traces the same rectangle the Ordnance Survey cartographers recorded nearly two centuries ago.
