At the northern end of a low pasture ridge in County Kildare, where the ground gives way to a wide expanse of bog, there is a small grass-covered mound that measures roughly ten metres by seven at its base and rises no more than half a metre above the surrounding field. There is nothing to suggest a church ever stood here, at least not to the casual eye. Yet the mound is almost certainly all that remains, above ground, of Killart Church, a site so thoroughly erased by time that by 1837 even local knowledge of it had become secondhand and uncertain.

The observation from 1837 comes from O'Conor, who co-compiled the Ordnance Survey Letters for County Kildare and noted, with careful qualification, that there was once a church called Killart of which only vestiges, as he had been informed, then remained. By that point, the physical evidence was already gone from view. Writing between 1899 and 1902, a researcher named Darby recorded a local tradition connecting Killart to a possible moated site roughly a mile to the south. A moated site, in Irish medieval contexts, typically refers to a raised platform surrounded by a water-filled ditch, often associated with manorial settlement. According to that tradition, monks from both Killart and the nearby church at Kilberry used the moated enclosure as a place of refuge, suggesting some period of threat or instability, though no date or detail is attached to the story. What survives today is the rectangular mound adjoining the graveyard to its southwest, where the ground rises to about 1.6 metres at the boundary, hinting at the buried architecture beneath the turf.
