The font now housed in the porch of St Joseph's Roman Catholic Church in Baltinglass, County Wicklow, is a displaced object, its original home the subject of local disagreement that has never been resolved.

Local tradition offers two candidate sites: the graveyard at Kilranelagh and that at Coolinarrig. The latter is considered the more plausible of the two, being closer to Baltinglass and lying within the bounds of the present parish. The font itself is a substantial piece of work, cut from a large, oblong block of granite measuring roughly 76 centimetres long and 75 centimetres wide. Its basin, straight-sided and oblong, is about 56 centimetres across and 20 centimetres deep, with a central drain-hole that has since been filled with concrete, a common modification when such fonts are moved into new settings where drainage is no longer needed or practical. Carved in bold relief on the side of the block is a cross, formed by a raised band approximately four to five centimetres wide, the cross itself standing about 23 centimetres high. It is a restrained, confident piece of carving, the kind of work that suggests considerable age without announcing it.
