It sits, technically, in pasture on a west-facing slope to the north-east of the river Blackwater, and it is known primarily because a cartographer recorded it in 1842. The Ordnance Survey map of that year marks it as a circular enclosure, the standard shape for a rath, the Irish term for a ringfort, which was typically a raised earthen bank enclosing a farmstead or defended homestead during the early medieval period. Today there is no visible surface trace.

That 1842 mapping is the only firm evidence that anything was ever here. Whether the enclosure was already fading when the surveyors passed through, or whether a century and a half of agricultural use subsequently levelled whatever remained, is not recorded. Ringforts are among the most common archaeological monuments in Ireland, with thousands identified across the country, yet many have been lost entirely to ploughing, drainage, and land improvement. This one at Dromidiclogh appears to belong to that category of sites that survive only on paper, a ghost of a feature in a field beside a river.
