The wall itself is unremarkable; what matters is what its construction disturbed and inadvertently preserved: three post-holes connected by a short trench, running roughly three metres in length, with layers of burning close by. Together, these fragments suggest a structure that once stood within the enclosure of St. Vogue's church, on the crest of a slope that would have looked out across the surrounding landscape.

Excavation at the site, recorded under reference E000143, uncovered these traces and was published by O'Kelly and colleagues in 1975. Post-holes are exactly what they sound like, the pits or sockets left in the ground when upright wooden posts decay or are removed, and when they appear in a line connected by a trench, archaeologists read them as the skeleton of a timber building. The burning layers found nearby may point to domestic use, or simply to the accumulation of ash and waste around a hearth. The structure sits roughly ten metres south-east of St. Vogue's church itself, within the ecclesiastical enclosure, which is the roughly circular or oval boundary, often still visible as a raised bank or wall, that would have defined the sacred and working space of an early Irish monastic or church settlement. That this possible house site occupies such a position suggests it may have been part of the original community associated with the church rather than a later, incidental addition.
