What survives is the top section of a twin-light ogee-headed window, the kind of opening, with its distinctive S-curved arch, most commonly associated with late medieval ecclesiastical building in Ireland. The present church around it appears entirely modern, and the graveyard itself contains no other early remains visible to the eye. The window fragment sits as an odd remnant, out of place and out of context, in an otherwise unremarkable setting.

The survival of architectural fragments like this one is not unusual in Irish churchyards, where later buildings were frequently erected on sites of continuous religious use stretching back centuries. An ogee-headed window of this type would be consistent with late medieval craftsmanship, suggesting the possible existence of a church here well before the present structure was built. No documentation of the earlier building appears to survive, and the fragment alone constitutes the physical evidence for what may have stood at Ballynure in the medieval period. Without further excavation or archival discovery, it is impossible to say more about the scale, date, or dedication of any church that once occupied the ground.
