Sitting on a rise along a north-facing slope in Caher, County Kerry, the rath sits in rough pasture with its views largely blocked by trees and encroaching vegetation, giving it a closed, interior quality unusual even among ringforts that have fallen out of use.

A rath is an earthen ringfort, a type of enclosed farmstead built predominantly during the early medieval period in Ireland, roughly between the fifth and twelfth centuries. Thousands survive across the country in varying states of preservation, but this one presents a notably uneven profile. The enclosure is roughly circular, measuring approximately 35 metres north to south and 34 metres east to west. Its defining bank survives to an external height of around 1.75 metres along the northwest to east-northeast arc, where trees now grow along its crest, though it drops to a mere 0.6 metres on the interior face. Elsewhere the boundary shifts character: a scarp running southeast to southwest, and an overgrown bank with several breaks completing the circuit to the northwest. The interior slopes noticeably downhill to the north, and the ground has been built up at both the southern and northern edges, by 0.4 metres and 1.15 metres respectively, as a practical response to the natural hillslope. A later field boundary, also earthen and tree-lined, cuts across the eastern side of the bank, truncating it and suggesting the enclosure was eventually absorbed into an ordinary agricultural landscape without anyone feeling the need to record the transition.
