It measures roughly twenty centimetres in length, barely ten centimetres deep, and carries on its surface two quiet details: diagonal tooling, the deliberate chisel marks a medieval mason would use to dress a stone to a finished face, and small patches of the lime plaster that once covered it. These traces suggest the jamb, the upright side-piece of a door or window frame, sat within a plastered interior, part of a building considered worth finishing properly.

The fragment is held in the Office of Public Works store in Kilkenny, catalogued as depot stone carving number KD016. Its three worked faces each run between seven and seven and a half centimetres wide, proportions consistent with a modest but carefully made architectural opening. Beyond its physical description, the notes are spare. Leggetsrath, a townland in County Kilkenny, has not left this particular stone with much of a documented history. What survives is the object itself, a small sandstone jamb removed from its original context and placed into institutional care, waiting to be understood more fully than the surviving record currently allows.
