The rath, a type of ringfort typically used as a defended farmstead during the early medieval period, sits on an east-facing slope with open views across undulating countryside, Killough Hill rising to the west. It is heavily overgrown now, its banks lost in places to vegetation, but the basic geometry of the place is still legible if you know what you are looking at.

The monument is a double-banked enclosure, meaning it was laid out with more than the usual single earthen rampart, suggesting its occupants either had reason to invest in extra defence or wished to signal status through elaboration. The interior measures roughly 28 metres across from north to south, with an overall diameter of about 60 metres taking in the outer works. That outer bank, where it survives, still stands 1.7 metres on its interior face. A fosse, the ditch dug to supply the material for the bank and to add an obstacle to any approach, runs between the two banks, and a second, shallower outer fosse was once present around most of the circuit. A sketch plan drawn up in the 1950s, held in Office of Public Works files, recorded this outer fosse running the full way around except for the north-west quadrant. Today it is only visible on the south side. The causewayed entrance, a gap in the earthworks where the original approach crossed the fosse on a raised strip of ground, survives at the north-east. The south half of the fort is noticeably better preserved than the north, where the road and tree-root damage have together reduced the outer bank to little more than a suggestion in the ground.
