The enclosure measures roughly 27.5 metres along its longer axis and is defined by a low, sod-covered bank of sandy soil, nowhere more than about 40 centimetres high and up to three metres wide. That modest profile is part of what makes the site puzzling. A bank so slight could never have functioned as a serious physical barrier; it may instead have served as the footing for a timber fence, now long gone, leaving only the earthen base behind. The interior is flat and essentially featureless, barely distinguishable in level from the surrounding ground, and the bank itself is most easily spotted by the slightly darker vegetation growing over it rather than by any dramatic rise in the landscape.

At the northern end of the enclosure the bank fades almost entirely, merging with a low, roughly rectangular platform of uncertain purpose sitting just outside the enclosure proper. Whether this platform is connected to the enclosure or represents something else entirely is not known. The function and date of the whole feature remain unresolved. Adding another layer of ambiguity is what the 1838 Ordnance Survey six-inch map shows immediately to the south: a lake, named Lackakeely Lough, roughly 100 metres across and draining northward via a stream. When the site was visited in recent years, the ground was dry and no lake was visible, though a small stream ran some 35 to 40 metres to the east. This points to the possibility that the lough is a turlough, the distinctively Irish phenomenon of a seasonal limestone-fed lake that fills during wet weather and disappears in drier periods, leaving behind ordinary-looking pasture. Whether the enclosure was built in relation to the lake, or was already ancient when the lake existed, or has nothing to do with it at all, is an open question sitting quietly in the grass.
