What survives of the parish church of Kill St Nicholas is, in a very practical sense, almost nothing: a low smear of spoil-covered foundations on a west-facing ridge slope, the ghost of a rectangular building roughly thirteen to fifteen metres long and fewer than seven metres wide. By 1615, a diocesan survey of the Protestant diocese of Waterford was already describing the nave and chancel as ruins, which means the building had likely been abandoned well before that date. The graveyard that once accompanied it, recorded on the Ordnance Survey's six-inch map of 1840 as a D-shaped enclosure of roughly fifty metres by twenty-five, has since been absorbed into the surrounding farmland, cut off at its southern edge by a field bank. No trace of burials remains visible.

What makes the site quietly arresting is not the church itself but the objects associated with it. A bullaun stone survives on site, a conglomerate boulder just under eighty centimetres long, with a single deliberately carved basin hollowed into its upper surface. Bullaun stones are a recurring feature of early Irish ecclesiastical sites; the basins, worn smooth over centuries of use, are thought to have served ritual or practical purposes, possibly the grinding of pigments or medicines, possibly the collection of water believed to have curative properties. A sandstone quern, used for hand-grinding grain, was also found here. About fifteen metres to the south-west, the site of St Nicholas' Well persists as a concrete-lined hollow, now overgrown, its dedication linking the place to one of the most widely venerated saints of the medieval church. The Rev. P. Power, writing on the ancient ruined churches of County Waterford in 1890 and 1891, noted the well in connection with this site, suggesting the pairing of church and holy well followed the familiar pattern of early Irish sacred landscape.
