Though no trace of the castle remains visible today, this location holds significant historical importance as the place where Edmund Mac Richard Butler commissioned a transcript of the prestigious Psalter of Cashel in 1453. The castle’s exact position has been identified in the southwest corner of what was once the farm and stable yard of Pottlerath House, though archaeological evidence above ground has long since vanished.

Edmund Mac Richard Butler, who ordered the important manuscript work at the castle, is also credited with constructing the nearby church around 90 metres to the north during the mid-15th century. His patronage of both religious architecture and scholarly transcription work suggests Pottlerath was once a centre of considerable cultural activity in medieval Kilkenny. The castle itself survived for several centuries before meeting its end around 1800, when it was deliberately demolished and levelled to the ground.

Historical records provide glimpses of the castle’s former presence in the landscape. According to the historian Carrigan, writing in 1905, the castle stood approximately 50 to 60 yards in front of Pottlerath House before its destruction. By 1839, when the Ordnance Survey Letters were compiled, observers noted that no vestige of the structure remained. The first edition Ordnance Survey map from that same year, along with the 1899-1900 revision, marked the castle’s location for posterity, ensuring that even though the physical structure has disappeared, its place in the historical landscape of Kilkenny remains documented.
