Yet tucked between the church known as St John the Baptist and the cathedral called Templemore lies something far easier to overlook: a scrap of foundation stonework, barely knee-high, whose purpose nobody has been able to determine.

What survives is a section of the north-east corner of a building, consisting of two foundation lines. The north wall runs east to west and measures just over three and a half metres in length, roughly ninety centimetres wide and thirty centimetres high. Off its eastern end, a shorter return of about one and a quarter metres extends southward, tracing the beginning of the east wall. That is all that remains. The building sat within the wider monastic enclosure at Kilmacduagh, a site traditionally associated with St Colmán mac Duagh, who is said to have founded a community here in the early seventh century. The complex grew over subsequent centuries into the collection of churches, a round tower, and ancillary structures that survive in various states of ruin today. Whether this particular building was a chapel, a domestic structure, a workshop, or something else entirely, the stonework no longer says.

Visitors walking between St John the Baptist and Templemore can look for the low foundation remains at ground level. They are easy to miss precisely because they are so fragmentary, which is in some ways their point of interest. In a complex where grander buildings announce themselves clearly, this corner of unknown function is a quieter, more ambiguous presence.
