Enclosures of this kind, earthwork or stone boundaries that once defined a settlement, a farmstead, or perhaps a ritual space, are scattered across Kerry in considerable numbers, yet each occupies its own particular corner of ground, shaped by whoever built it and whatever purpose drove them.

The site at Cappagh is catalogued in the Archaeological Inventory of County Kerry, a systematic survey of south-west Kerry compiled by Aidan O'Sullivan and John Sheehan and published in 1996. That volume remains one of the more thorough regional archaeological inventories produced for any Irish county, recording hundreds of monuments across a landscape that has been continuously inhabited, farmed, and reshaped since prehistory. Cappagh itself is a small rural townland, and the enclosure it contains is the kind of feature that can easily read as a low grassy bank or an irregular field boundary to an untrained eye, its original form softened by centuries of weathering and agricultural activity.
