It is easy to miss, and that is partly the point. Ring barrows are prehistoric burial monuments, typically consisting of a central mound enclosed by a surrounding ditch, or fosse, and an outer earthen bank, the whole arrangement forming a kind of layered circle around the remains of the dead. This one measures just over nineteen metres in diameter, with the central mound rising to a modest maximum height of around three-quarters of a metre. It is not dramatic in scale, but the form itself carries considerable age.

The monument is in fair condition overall, though it has been noticeably worn away on its south-eastern side, most likely through centuries of agricultural activity or simply the slow work of weather and root systems. The trees and bushes that now grow around and across the site give it a slightly overgrown, half-reclaimed quality. What makes the Raheen barrow particularly interesting is its company. Another barrow of the same type lies roughly 260 metres to the north-east, and a third sits just 60 metres to the south-west. This clustering is not unusual for the prehistoric landscape of the west of Ireland, where such monuments were often placed in loose groupings across ridges and slopes, suggesting that the living chose these elevated positions carefully, both for visibility and, presumably, for meaning.
