Aerial photographs taken in 1966 and 1969 reveal its outline clearly enough, but no trace of it survives at ground level, and researchers believe it has no connection to the tower house standing nearby. What it once enclosed, and why it vanished so completely, remains an open question.

The tower house itself, a form of compact fortified residence common across medieval Ireland, was already a ruin by the mid-seventeenth century. The Civil Survey of 1654 to 1656, a detailed land record compiled under Cromwellian administration, described the site as holding nothing more than 'the stumpe of an old castle and the ruines of an old Mill all wast'. At that time the proprietor was recorded as Thomas Butler of Kilconell, designated 'Irish Papist', a label used in the survey to mark Catholic landowners who were subject to dispossession under the Cromwellian settlement. The structure that stands today is three storeys of roughly coursed limestone rubble, with punch-dressed quoins, meaning the corner stones were finished with a toothed chisel to produce a textured face, and a slight base-batter, a gentle outward slope at the base of the wall that was a standard feature of tower house construction to add stability. What visitors see now reflects heavy modification carried out during the eighteenth and nineteenth centuries, so the building's current form owes at least as much to those later interventions as to its medieval origins. The site sits on a slight rise of rock outcrop in quietly rolling north Tipperary farmland, an unremarkable elevation that would nonetheless have made the original structure visible across a considerable distance.
