Roughly 0.3 metres wide, perforated through its centre, and carved on all four sides with a roll moulding flanked by filleted keel moulding at the angles, the piece is easy to overlook among the headstones. It may once have served as a baptismal font, the kind of wide-lipped basin in which water was blessed and infants received into the church. If that identification is correct, it is a physical remnant of a medieval place of worship that has otherwise left almost no trace above ground.

The church it may have belonged to, known in Irish as Teampall Inse, appears in the Papal Taxation List of 1302 to 1307 under the diocese of Ardfert, listed as 'Eccia de Inse'. The Papal Taxation was a Europe-wide ecclesiastical survey that assessed the income of church properties, and its appearance in that document places Inch among the recognised parish foundations of medieval Kerry. There is, however, a complication. Scholars have debated whether 'Eccia de Inse' refers to a thirteenth-century church at Inch itself or to a foundation on the Great Blasket Island, several miles offshore. A further entry in the same taxation, a church recorded as 'Baliederscolle' from the year 987, has also been proposed as a reference to the Inch site, pushing its origins back considerably further. None of these identifications has been settled conclusively, which means the small carved stone sits at the intersection of at least three competing histories, any one of which might be its own.
