The mound’s surface undulates irregularly, making its precise boundaries tricky to define in places, whilst numerous unmarked gravestones dot its uneven surface. One particularly intriguing feature is a stone slab on the western side that contains a small oval perforation, measuring roughly 6.5 by 4 centimetres; its purpose remains a mystery, though such openings sometimes served ritual or symbolic functions in early Christian contexts.

The most remarkable artefact associated with the site sits not on the mound itself but in a ditch along a field boundary to the southeast. Here lies a cross-slab measuring 1.6 metres tall with arms spanning 30 centimetres, its face decorated with a simple cross carved in relief at the centre of a broad, cross-shaped groove. This style of carving suggests an early medieval date, typical of the period when Christianity was establishing itself across Ireland through a network of small religious sites and burial grounds.

The graveyard’s setting adds to its atmospheric quality, surrounded by woodland to the south and west, with pastoral fields stretching eastward and the sea visible to the north. This location, typical of early Christian sites in Ireland, would have offered both practical advantages and spiritual significance to the community it served. The combination of the burial mound, mysterious perforated stone, and decorated cross-slab hints at centuries of continuous use, from perhaps pre-Christian times through the medieval period, making Kilmacanny a palimpsest of Irish burial traditions.
