The walls, sod-covered and grass-grown, measure roughly fifteen metres from east to west and six and a half metres from north to south. The western wall still stands to an external height of about one and a half metres, stone-faced on the outside, and the southern wall has been quietly absorbed into a roadside fence, making part of the structure a working boundary rather than a visible monument. There are no burial markers, no discernible churchyard, and no surface trace of a burial ground at all.

A description recorded around 1700, and later cited by Brady in 1863, offers a snapshot of the place when it was ruinous but still legible: the walls of a church or chapel called Killbarry, built with stone and clay, were standing uncovered, and the bounds of the churchyard were said to be discernible. The same account attributes the building to the Learys, describing it as a chapel of ease. A chapel of ease was a secondary place of worship, built to serve parishioners who lived too far from the parish church to attend regularly, so the structure on Kilbarry Hill would have functioned as a practical convenience rather than a primary ecclesiastical centre. That the Learys, a prominent Gaelic family in the region, were credited with its foundation suggests a degree of local patronage typical of late medieval Irish religious life. By the time anyone thought to write it down, the chapel had already been abandoned long enough for its origins to pass into local tradition rather than living memory.
