It measures roughly 68.5 metres north to south and 73 metres east to west, making it a substantial feature by any reckoning, yet its defining elements, a low earthen bank and a shallow external fosse, have been swallowed by decades of thorny scrub and uneven pasture. A fosse, in this context, is simply a ditch dug to the outer edge of the bank, a standard feature of early Irish enclosures that would once have reinforced the boundary both physically and symbolically. Here, that ditch runs along the northern and south-eastern sides, while the western quadrant retains the clearest stretch of surviving bank, rising about 0.9 metres above the exterior ground level and spanning 2.7 metres in width.

The enclosure's shape and scale place it within a broad category of large earthwork enclosures found across Ireland, often associated with early medieval settlement, ritual use, or territorial marking, though without excavation it is impossible to say with certainty what purpose this particular example served. The north-eastern quadrant has not survived intact; a field boundary running north-west to south-east has cut through it, and a townland boundary follows the northern perimeter, suggesting the old earthwork was absorbed into later land divisions rather than deliberately cleared away. The interior slopes with the natural hillside and the ground is uneven both inside and out, offering no obvious traces of structures at surface level. What makes the Clarabricken site quietly compelling is that it does not stand alone: a second, similar enclosure lies approximately 190 metres to the north-west, raising the possibility that the two were laid out in relation to one another, though whether they were contemporary or connected in function remains an open question.
