The earthen banks that define this enclosure at Ballysallagh are worn to barely half a metre in height, and the south-eastern side has disappeared entirely, leaving an open gap of some ten metres where whatever original boundary once stood has long since vanished into the grass.

The site is sub-rectangular in plan, measuring roughly 30 metres on its longer north-west to south-east axis and 18 metres across. The surviving bank on the north-west side retains a top width of 2.5 metres and an overall width of just over ten metres, suggesting it was once a more substantial earthwork than what is visible today. The south-western side is formed by a right-angled return of bank, some 20 metres long, which curves slightly rather than holding a perfectly straight line. A narrow gap of around 1.75 metres interrupts the curvilinear bank on the western side, which may represent an original entrance, though the record compiled by Denis Power and uploaded to the national monument register in November 2013 does not speculate beyond the physical description. Enclosures of this kind, broadly defined as areas bounded by earthen banks or ditches, appear widely across the Irish landscape and can date from the prehistoric period through to early medieval times, sometimes serving as farmsteads, animal pounds, or ceremonial spaces. What is notable here is that a second enclosure lies immediately to the north-east, suggesting the two features may have functioned together, though again the surviving evidence does not allow firmer conclusions.

The field in which the monument sits is incorporated into working pasture, so the earthworks are grazed rather than fenced off or otherwise marked. The stream to the east causes periodic flooding, which has likely contributed to the low and degraded profile of the surviving banks. Visitors approaching across damp ground after rain should expect soft footing throughout. The interior of the enclosure is generally level, and the monument is most legible from the north-west side, where the bank is best preserved and the slight change in ground level becomes apparent on close inspection.
