That omission is quietly remarkable. The surveyors were generally thorough, and yet this feature, measuring approximately 30 metres north to south and 27 metres east to west, escaped their attention entirely, leaving it to aerial photography taken more than a century and a half later to bring it back into view.

A barrow, in this context, is a burial mound or funerary earthwork, typically prehistoric in origin, defined by a raised bank enclosing a circular area. The example here lies roughly 170 metres southeast of the Barnakyle River and about 200 metres north of Elmpark House, and sits within a hundred metres of another recorded barrow to the east. Its outline was identified by researcher Fiona Rooney using Digital Globe aerial photographs taken between 2011 and 2013, alongside Global Earth orthoimages from 2009 and 2018. A separate trace of a bank running northwest to southeast is also visible on these images, located about 7 metres to the north of the main circular feature. The site was formally uploaded to the archaeological record in June 2020. Whether the earthwork survived unnoticed because it sits in unassuming pasture, or because its low profile made it easy to overlook from the ground, is not clear from the available record.

The site is on private agricultural land within the Elmpark demesne, so access would require the landowner's permission. It is not signposted or managed as a heritage site. The most revealing views remain the aerial ones, and anyone with an interest in the feature would do well to examine the Google Earth orthoimages from November 2019 and May 2018, where the circular bank and the faint northern trace are most legible. On the ground, in low pasture, the earthwork would likely read as a subtle rise rather than anything dramatic, the kind of thing that rewards patience and a low sun angle rather than a quick glance from a road.
