The ravine drops away where a conventional bank would otherwise run, so whoever built this place was content to let natural geography do part of the work. What survives is an enclosure roughly thirty metres across, defined by an earth and stone bank two metres wide, its outer face rising between one and three metres above the surrounding ground while the interior face stands considerably lower, barely above ankle height in places. In some sections the bank has been worn down to a simple scarp, a sloped edge rather than a built-up wall.

The fort sits in upland country already crowded with early medieval remains. Immediately to the west lie a motte and a ringfort, the motte being a flat-topped earthen mound of the kind introduced to Ireland by the Normans from the late twelfth century onwards, typically carrying a timber tower and enclosed yard above. The clustering of different monument types, a cliff-edge enclosure alongside a ringfort and a Norman motte, suggests that this stretch of upland was considered strategically or symbolically significant across several centuries of use. Inside the enclosure, a deep rectangular hollow measuring fifteen metres east to west and six metres north to south, and dropping roughly two metres below the surrounding surface, is most likely the result of quarrying rather than any deliberate architectural feature, though its presence gives the interior an unexpectedly sunken, excavated quality.
