A ring-barrow is a circular burial mound, typically of prehistoric origin, defined by a surrounding ditch and low bank. This one sat on a gently south-facing slope in pasture just north of a promontory fort, a type of coastal enclosure in which a headland is cut off by a bank and ditch to form a defended site. The two features in close proximity already made this a quietly layered landscape. What happened next made it stranger still.

When Markus Casey visited the site in May 1992, all three ring-barrows in the area were noted as present. By 2003, however, inspection revealed that extensive quarrying had taken place at the adjacent promontory fort, and the ground where this particular barrow once stood had been quarried away. The spoil heaps produced by that quarrying were then deposited immediately to the north of the disturbed area, and it is considered possible that the monument now lies beneath them, effectively sealed under the rubble of activity that destroyed its visible surface. The other two ring-barrows in the group remain extant as of 2019, sitting 65 metres and 140 metres to the north and north-north-west respectively, close enough to give a sense of what this one may once have looked like. The site carries a preservation order under the National Monuments Acts 1930 to 2014, though that designation arrived, as it sometimes does, after the most significant damage had already occurred.
