It sits instead in the Pitt-Rivers Museum in Oxford, a long way from the old churchyard of Kilnaughtin where it spent an unknown number of centuries lying quietly in the ground.

Ogham is an early Irish script, typically carved as a series of notches and strokes along the edge of a stone, and most surviving examples date from roughly the fourth to the seventh centuries. This particular stone was discovered in 1836 by John Windele, the Cork antiquarian and prolific recorder of ogham inscriptions, who found it lying about six feet from the south-east angle of the church within the burial ground. The stone is modest in size, roughly 75 centimetres long and 15 centimetres wide, and what survives of its inscription is fragmentary. Macalister, who catalogued it in his 1945 corpus of ogham inscriptions, read it as ending in MAQI BROCI, with earlier characters lost. MAQI is the ogham genitive form of "son", appearing in countless such memorial formulae, while BROCI would be a personal name, possibly related to the Old Irish word for badger. The beginning of the inscription is gone, so the name of the commemorated individual remains unknown.

The stone's removal from its original context is not unusual for the period. Many Irish ogham stones were acquired by collectors and institutions during the nineteenth century, and the Pitt-Rivers Museum holds a number of such pieces. The churchyard of Kilnaughtin, on the Carhoona townland boundary, still exists in Kerry, but anyone hoping to find this particular stone there will be disappointed.
