It appears on a map from 1897, and then, for practical purposes, it disappears. By the time satellite imagery was taken between 2011 and 2013, neither Digital Globe nor Google Earth could detect any surface remains. The land had simply moved on without it.

What the 1897 edition of the Ordnance Survey Ireland 25-inch map recorded was a raised, roughly circular area approximately 26 metres in diameter, defined by a scarp, a steep slope or edge in the ground, running from south through north to south-east, with an external fosse, essentially a ditch, along the north-east to south-east arc. Features of this kind are broadly consistent with a ringfort or enclosure type common across Ireland, where a raised interior platform and surrounding ditch once defined a farmstead or defended enclosure, typically dating to the early medieval period. Notably, the feature does not appear at all on the earlier 1840 edition of the OSi 6-inch map, which raises questions about whether it was simply overlooked by the earlier surveyors or whether its visibility had already begun to diminish by the mid-nineteenth century. A field boundary running north-east to south-west had already truncated the south-east edge of the earthwork by the time the 1897 map was drawn, suggesting agricultural pressure had been working against it for some time. The site lies roughly 140 metres south-west of a stream that marks the boundary between Inchacoomb and the neighbouring townland of Boolanlisheen. The record was compiled by Martin Fitzpatrick and uploaded in October 2021.

For anyone curious enough to look, the site is in reclaimed pasture and there is nothing on the surface to reward a visit in the conventional sense. The earthwork survives, if at all, only as a subsurface anomaly, detectable perhaps by geophysical survey but not by walking the field. The value here is less in the place itself than in what the cartographic record reveals about how quickly even a reasonably substantial circular enclosure can be absorbed into improved agricultural land within a few generations. The 1897 OSi 25-inch map series, available through the OSi historical map viewer, remains the only source that fixes this feature in the landscape with any confidence.
