It is easy to miss, set into the wall rather than displayed at eye level, and its modest dimensions, roughly 58 centimetres wide and 24 centimetres high, do nothing to announce themselves. Yet the carving it carries is a quiet piece of early ecclesiastical craft.

The cross itself is an equal-armed form with expanded terminals, meaning each arm of the cross widens slightly at its tip, a design found across early medieval Irish stonework and associated with the period when Christianity was being worked into the visual language of stone. According to Dr J. Waddell, who recorded the piece, the cross is small and roughly executed, which places it closer to the vernacular end of early Christian carving than to the elaborate high crosses more commonly associated with major monastic sites. Its position above the window arch on the internal face of the east gable, the liturgically significant end of a church oriented toward Jerusalem, suggests it was not incidental decoration but a considered placement, marking sacred space within the building.
