The site sits approximately 230 metres from the stream that runs north-northwest to south-southeast through the valley below. Though nothing remains visible at ground level today, historical records confirm a castle stood here during the turbulent mid-17th century.

The castle appears in Ireland’s Civil Survey of 1654-6, a comprehensive land survey undertaken during the Cromwellian period. According to these records, the castle and its lands belonged to Philip Rowe in 1641, just before the outbreak of the Irish Confederate Wars. The survey, compiled in the aftermath of these conflicts, provides one of the few surviving references to this lost fortification; its inclusion suggests the structure held some significance in the local landscape at the time.

Today, visitors to the site will find only an empty pasture where the castle once stood. The complete disappearance of the structure above ground speaks to centuries of stone robbing, agricultural use, and natural decay that have erased most physical traces of Hacketstown Castle. Archaeological investigations might yet reveal foundations or other subsurface features, but for now, the castle exists primarily in the historical record, a reminder of how much of Ireland’s built heritage has vanished from the landscape.
