This one, in the townland of Ballycullane in County Limerick, has managed to avoid all of that, and may no longer exist at all. What is recorded here is less a surviving structure than the ghost of one: a possible cairn, a cairn being a mound of stones typically raised over a burial or as a landscape marker, noted in passing in 1976 and since swallowed, in all likelihood, by the surrounding farmland.

The National Museum of Ireland's Topographical Files contain the only substantive record of the site. A survey visit in 1976 noted what was described as "another spread slightly raised above field level," the careful hedging of that language suggesting even then that the feature was barely distinguishable from its surroundings. The note also refers to a third cairn in the vicinity that was mentioned but could not be located at the time. A possible companion monument lies roughly 50 metres to the west, recorded separately under its own reference. None of these features appear on Ordnance Survey Ireland's historic mapping, which places them outside the tradition of officially recognised archaeological landmarks. When later aerial photography and satellite imagery were consulted, nothing was visible on the ground. The field has since been reclaimed as pasture, and the working assumption among those who have looked into it is that whatever low mound once existed has been levelled.

For anyone curious enough to seek out the general area, Ballycullane sits north of the townland boundary with Cahirguillamore, in a stretch of ordinary agricultural country that gives little outward sign of any former significance. The site itself, positioned around 8 metres south of a field drain, offers nothing visible to the eye today. What makes it worth knowing about is precisely that absence: the 1976 photograph held in the NMI Topographical Files represents what may be the only surviving record of a feature that has since been erased from the landscape entirely. It is a reminder that the archaeological record is always incomplete, and that reclamation of farmland has quietly removed a great deal that was never formally catalogued before it disappeared.
