Historical records from the 1659 Down Survey maps show the castle positioned beside the medieval church of Rathaspick, with the parish terrier noting that the structure was still ‘in repaire’ at that time. This suggests the castle remained functional well into the 17th century, serving as an important fortification in the Moygoish barony during a turbulent period of Irish history.

The site where the castle likely stood can be found east of Rathaspic House and roughly 70 metres south of Rathaspick Church. Whilst the 1837 Ordnance Survey six-inch map clearly marks ‘Site of Castle’ in the area east of Rathaspic House, no physical traces of the structure survive today. Neither cut stone from the original building nor any visible foundations remain, and extensive searches of Rathaspic House and its outbuildings have revealed no incorporated medieval masonry that might have been salvaged from the castle ruins.

Despite its complete disappearance from the landscape, the castle’s documented presence on multiple historical maps confirms its significance to the local area. The fact that it was recorded as being in good repair as late as 1659 makes its total obliteration all the more intriguing, leaving historians and archaeologists to piece together its story from cartographic evidence alone. The castle’s proximity to the medieval church suggests it may have played both defensive and administrative roles in the parish, though without archaeological excavation, the full extent of its importance to medieval Rathaspick remains tantalisingly out of reach.
