A cairn, which in the Irish archaeological context typically refers to a mound of stones covering a prehistoric burial or marking a significant site, appears on the first edition Ordnance Survey six-inch map of 1840 as a small mound roughly ten metres in diameter. Today, that feature is no longer visible at ground level. The land has been reinstated as pasture on a south-west-facing slope within a former quarry, and whatever remains of the cairn lies undetected beneath the grass.

The story of its disappearance is fairly typical of the mid-twentieth century agricultural reshaping of the Irish countryside. According to local information, a structure referred to as a "fort" once stood in this field; enclosures of this kind were a common feature of early medieval Ireland, usually consisting of a raised ringfort or earthen bank enclosing a settlement or farmstead. The surrounding field boundaries were removed during the 1960s, and the feature may have been levelled at the same time. By 1974, when an aerial photograph was taken, only a small circular anomaly was detectable, visible to the south-east of a nearby enclosure. That faint shadow in the cropmarks or soil discolouration is now the most tangible record of what once stood there, alongside the 1840 map notation made before the damage was done.
