The western bank is missing, and the likely explanation is quietly mundane: material was almost certainly robbed out to build a cart track that still passes close by on that side. It is the kind of erasure that happens incrementally, without drama, and it means the enclosure now survives only partially, its outline legible but incomplete. What makes it stranger still is that it does not appear on Ordnance Survey maps at all, belonging to a group of monuments that cartographers, for whatever reason, simply left off.

This enclosure is recorded as monument No. 12 within a complex of twelve monuments at Cahercorney, first documented systematically by O'Kelly in the early 1940s. Writing in 1942 to 1943, O'Kelly described it as measuring roughly 75 feet north to south and 40 feet east to west, situated close to what he called platform No. 8, another feature within the same marsh complex. Of the twelve monuments in the group, all except the first five are set within this low-land marsh environment, and several, including this one, were never captured on the standard mapping of the area. The site carries the reference LI032-073001-/013- in the Archaeological Survey of Ireland records, and an aerial photograph taken in January 2003 under reference ASIAP 344/10 provides one of the clearer modern views of what survives.

The marshy ground makes this a site that rewards patience and appropriate footwear rather than a casual detour. The landscape itself offers few visual landmarks, and because the monument is absent from OS maps, locating it requires either consulting the Archaeological Survey of Ireland database directly or cross-referencing O'Kelly's published descriptions with the aerial photography record. The earthworks are subtle at ground level, the mound being very low and the surrounding features worn down considerably, so visiting in late autumn or winter, when vegetation dies back, gives the best chance of reading the shape of the enclosure in the land. What you are looking at, if you find it, is the edge of a much larger ceremonial or settlement landscape, most of which also remains incompletely understood.
