But at one point the surface shifts almost imperceptibly, describing the ghost of an oval enclosure roughly 21 metres east to west and 19 metres north to south. The low earthwork that marks it, a scarp no more than 20 centimetres high in places, is so subtle that it reads less as a structure than as a memory of one pressed into the soil.

Enclosures of this kind are among the most common archaeological monuments in the Irish landscape, typically interpreted as the enclosed farmsteads of early medieval ringfort builders, though the term covers a range of functions and periods. What survives here is fragmentary: the scarp is best preserved along the southern and eastern arc, and intermittent traces of a fosse, a shallow external ditch originally dug to reinforce the boundary, can still be detected. The western side has been cut across by what appears to be a later drainage channel, which has truncated the monument and removed any clarity it might once have had in that sector. The levelled remains of old field boundaries to the north-west and north-east suggest that the wider agricultural landscape around the enclosure has itself been substantially reworked over time, leaving this slight oval as one of the few legible remnants of an earlier pattern of land use.
