That last detail is what gives the site its particular strangeness: no obvious gap breaks the ring of the bank, no worn path or causeway crosses the fosse, the outer ditch that encircles it. Whatever this enclosure was for, it was not designed, or at least did not survive, in a way that makes its use self-evident.

The structure itself is a near-perfect circle, roughly 35 metres in diameter. An earthen bank, between four and five metres wide, forms the boundary, rising to about 0.8 metres above the interior ground level. On the western side, where the earthwork is best preserved, the outer face climbs to a more imposing 2.3 metres above the base of the fosse. That fosse, a flat-bottomed external ditch, measures around 2.4 metres across its base and drops to nearly 1.9 metres deep on the west, though it becomes considerably shallower and less distinct as it curves around to the east, where it reaches only about 0.8 metres in depth. This asymmetry is common in earthworks where centuries of erosion and soil creep have affected the more exposed or lower-lying sides differently. Embanked enclosures of this kind are found across Ireland and belong to a broad and not fully understood category of earthen monuments; some served as ringforts, the farmstead enclosures of early medieval Ireland, while others may have had ceremonial, funerary, or pastoral functions. Without excavation, this one in Ralph keeps its category ambiguous.

The scrub cover that now fills the interior makes close inspection difficult, but the bank and fosse are reportedly legible to someone willing to walk the circuit. The western arc, where the external height is greatest, gives the clearest sense of the original effort that went into throwing up this earthwork on a slope that would already have required careful planning to level and drain.
