It is the kind of object easy to overlook, yet its proportions have been recorded with some care: roughly 58 to 59 centimetres across, standing between 30 and 36 centimetres high, with a circular hollow cut into its top face. That hollow has near-vertical sides, a rim that shifts between flat and rounded depending on where you measure it, and no drain hole, which suggests water was held rather than allowed to escape.

The stone is reputed to have come from an ancient church site at Chapel in County Wicklow. Baptismal fonts of this type, hewn directly from a single block of local stone, are among the more durable remnants of early ecclesiastical sites in Ireland, where above-ground structures of timber or unmortared stone often disappeared entirely while the carved stonework survived. The absence of a drain hole is a detail worth noting: in fonts designed for full immersion or substantial pouring, drainage was often unnecessary, the water being changed by hand. Whether this piece dates to the early medieval period or somewhat later is not recorded, but its association with a named church site gives it a context that plain dimensions alone cannot supply. It is now held privately, having been removed from its original location at some point before any formal record was made.
