It is a ring barrow, a type of prehistoric funerary monument in which a low mound or flat interior is enclosed by a surrounding ditch and an outer bank of upcast earth, giving the whole structure a subtle, concentric form when seen from above or in raking light.

This particular example at Inchafune measures eight metres across in both directions, making it a modest but well-defined specimen. A shallow fosse, the encircling ditch, survives to a depth of around 0.65 metres, and the external bank still stands to roughly 0.8 metres on its northern to southern arc. The interior is level, which is characteristic of the ring barrow form and distinguishes it from the more familiar bowl barrow, where a central mound is the dominant feature. Ring barrows are generally associated with the Bronze Age, though they span a broad period and their precise function, whether for primary burial, secondary commemoration, or repeated ritual use, often varies from site to site. The low-lying setting beside a river is not unusual for such monuments; water boundaries held clear significance in prehistoric thinking about the boundaries between worlds.

The site sits in ordinary farmland, and the earthwork's modest profile means it reads more as a slight unevenness in the pasture than as a dramatic monument. The bank survives best along its northern and southern extent, and the shallow ditch is the clearest indicator of the structure's true shape on the ground.
