These are prehistoric barrows, low earthen funerary mounds typically ringed by a shallow ditch, that sit so close to the level of the surrounding pasture that a person could walk across them without the faintest suspicion that anything lay underfoot. What gives them away, if anything does, is a subtle trick of the season: the ditch that encircles each mound tends to collect moisture, and after rain the grass growing in it turns a fresher, brighter green than the pasture around it. A circle of slightly greener ground is, in many cases, all that remains visible of a burial monument that has endured for millennia.

In 1934, the archaeologist S. P. Ó Ríordáin visited Lissard and recorded numerous examples of these monuments across the townland, publishing his findings in 1936. He noted that the mounds were so slight, and the rise to their centres so gradual, that the sunken ring of the ditch was consistently the most legible feature. The following year, in 1935, he excavated one barrow located roughly 60 metres to the north-west of this particular example, the only one in this cluster to have been examined below ground. What Ó Ríordáin documented here was not an isolated monument but part of a dense funerary landscape. This barrow is one of eleven concentrated within a roughly 240 by 230 metre area in the south-west corner of Lissard townland, and two further barrow cemeteries occupy fields immediately to the west and north. Despite this concentration, none of the monuments appear on historic Ordnance Survey Ireland maps, suggesting they were already so reduced by the time of the surveys that cartographers simply did not see them.

The site sits in reclaimed pasture, and the practical reality for anyone visiting is that surface remains are extremely faint. Satellite imagery taken between 2011 and 2013 showed no visible traces at all, while a Google Earth image from November 2018 revealed only a faint impression. The best conditions for spotting any ground-level trace are likely after sustained wet weather in late autumn or winter, when the differential moisture in the ditch ring has the best chance of showing up in the vegetation. There is no visitor infrastructure here; this is agricultural land, and any visit would require both landowner permission and a willingness to look very carefully at what appears, on the surface, to be an ordinary field.
