Where a ringfort, or rath, typically describes a roughly circular area enclosed by one or more earthen banks, this enclosure takes a flattened, D-shaped plan, a variation that archaeologists occasionally encounter but that remains comparatively rare and not fully understood.

The site is recorded in O'Sullivan and Sheehan's archaeological inventory of south-west Kerry, published in 1996, which catalogues the dense concentration of early medieval and prehistoric monuments found across this part of the peninsula. Kimego itself is a small townland, and the enclosure represents one of the many field monuments that survive in this landscape, often overlooked simply because Kerry contains so many of them. The D-shaped plan may reflect the natural topography of the ground, with a field boundary, a slope, or a water feature providing one straight or flattened side in place of a continuous earthen circuit, though the specific reasons here are not recorded.
