This one earned its place, at least partly, by being doubted. In the reclaimed pasture of Feloree townland in County Limerick, there is a location registered as a possible ring-barrow, a type of prehistoric funerary monument consisting of a burial mound enclosed by a circular ditch or bank. The entry exists on the national record, but the evidence for what it actually is remains genuinely uncertain, which makes it an oddly honest example of how archaeology works in practice.

The site was first identified during the Bruff aerial photographic survey of 1986, when a small circular cropmark showed up in the imagery, catalogued as Bruff 24, AP 4/3665. Cropmarks appear when buried features affect how vegetation grows above them, revealing outlines invisible at ground level. In this case, the circular form suggested a ring-barrow, and the surrounding landscape gave some reason to take that seriously: a confirmed ring-barrow lies just 27 metres to the north, and linear earthworks sit 48 metres to the south-east. The site does not appear on any historical Ordnance Survey mapping, which might simply mean it had been levelled or obscured before those surveys were made. But when later imagery was examined, including an Ordnance Survey Ireland orthophoto from 2005 to 2012, the cropmark had disappeared entirely. A possible faint trace reappeared on a Google Earth image taken in June 2018, though even that remained inconclusive. Fiona Rooney, who compiled the record and uploaded it in July 2020, noted plainly that the original cropmark was unconvincing evidence, and that the feature might equally be related to land drainage or to a natural geomorphological process in the soil.

There is nothing to see here in the conventional sense, and that is precisely the point. The location sits between two streams that mark townland boundaries, one to the west separating Feloree from Boherroe, one to the east bordering Ballyphilip. For anyone curious enough to visit the general area, the confirmed ring-barrow 27 metres to the north is the more tangible draw. The Feloree site itself is farmland, and its significance lies less in what is there than in the question of whether anything is there at all, a question that aerial photography raised in one dry summer and subsequent imagery has not yet settled.
