The burial ground at Kiltegan sits on the crest of a hill and spills down part of its south-western slope, bounded by an enclosure that is, on closer inspection, not quite what it seems. The northern and western sides of the boundary run straight, as later field-making tends to demand, but the southern and eastern sides curve, tracing an arc that belongs to an earlier phase of the site altogether.

By the time the first edition Ordnance Survey six-inch map was made in 1840, the site was already recorded simply as a burial ground, its earlier religious identity reduced to a label on paper. But the physical evidence is more suggestive. At the centre, slightly west of middle, stands the much-reduced ruin of a church; so denuded now that it reads more as a low presence than a standing structure. About two metres beyond the straight northern boundary wall, on the outside, there is a curving earthen bank that may preserve the original line of the ecclesiastical enclosure, the kind of roughly circular boundary that typically surrounded an early Irish church and its associated settlement. Such enclosures, modest in height and easy to overlook from a distance, are among the most consistent markers of early medieval religious sites in Ireland. This one survives only partially; ploughing in the fields to the north and west has erased whatever continued there. A further internal bank runs north to south near the western edge of the graveyard, and in the field immediately south of the enclosure a low rectangular platform, roughly 19 metres by 41 metres and defined by a scarp on its southern and western sides, hints at structures or activity beyond the graveyard boundary whose purpose is no longer clear.
