It measures around thirteen metres east to west and ten and a half metres north to south, defined by the remnants of a stone wall that, in places, was carefully engineered to cope with a sloping site. Where the ground rises to the south, the wall was cut directly into the bank; where the slope falls away to the north-west, builders compensated by raising the external face with a combination of earth and stone to maintain an even height. That kind of practical adaptation to difficult terrain is easy to overlook in a ruin, but it speaks to a considered piece of construction.

The best-preserved section runs along the south-western arc, where the wall still shows traces of its original design: an inner and outer row of upright stones set closely together, with rubble packed between them. This double-faced construction with a rubble core is a technique associated with prehistoric and early medieval enclosures across Ireland, used to create a wall of some solidity without the need for mortar. Elsewhere around the circuit, particularly from the north-west to the east, the wall has largely collapsed, its stones sliding down the outer bank face and leaving only low, intermittent traces. The interior slopes gently northward and is now rough pasture. The enclosure sits at the south-eastern end of a broader network of field boundaries on the same hillside, suggesting it was once part of a more extensive system of land division rather than a standalone structure.
