It is easy to miss entirely, absorbed as it is into the fabric of a working pub interior, yet it carries a considerable amount of history with it, having passed through at least two buildings before arriving at its current resting place behind the hearth.

According to local knowledge, the stone originated at a seventeenth-century building in the townland of Cully, the same structure that appears on the 1838 edition of the Ordnance Survey six-inch map labelled as the "Convent in Ruins". At some point it was removed from that site and acquired by Derrymore House, a nineteenth-century townland house nearby, before eventually being incorporated into the pub. The stone is dressed using a pocked tooling technique, a method of finishing stone by striking the surface repeatedly to create a roughened, dimpled texture, and this treatment is described as closely resembling the workmanship visible on the doorway of Srah Castle, a tower house in the same general area of Offaly. That visual connection hints at a shared craft tradition, and perhaps a shared workshop or mason, working in the region in the mid-seventeenth century. Whether the date 1641 marks a construction, a renovation, or something else entirely, the stone itself offers no further explanation, which is part of what makes it so quietly compelling. The year falls in the immediate run-up to the Irish Rebellion of 1641, a period of considerable upheaval across the country, though the stone carries no obvious record of any of that.
