The mound is roughly twenty metres across and rises between just under a metre and a metre and a half at its highest point, modest dimensions that might easily lead a passerby to read it as nothing more than a slight swelling in the field. But the surrounding berm, a flat platform two and a half to four metres wide that rings the mound before dropping away at a low scarp, marks this out as a ring barrow, a type of prehistoric funerary monument in which a central mound is enclosed by a circular earthwork, often associated with Bronze Age burial traditions.

The geometry of the site has a few details worth pausing over. The base of the monument, measuring roughly twenty-seven to twenty-eight metres across, has been cut back sharply at the north-west, leaving a straight edge approximately fourteen and a half metres long that runs parallel to a field bank ten metres away. Whether that truncation is ancient or the result of later agricultural activity is not clear from what survives at ground level. There is no visible fosse, the term for the ditch that typically accompanies such earthworks, and no obvious entrance. What there is, eight metres to the south of the mound, is a single earthfast stone of oval cross-section, about a metre long, sixty centimetres wide, and eighty centimetres above ground. Stones like this, set into the earth close to prehistoric monuments, are found at a number of Irish sites, though their precise relationship to the monuments beside which they stand is rarely straightforward. It is also worth noting that the mound itself may simply be the natural hillock shaped and defined by the surrounding earthwork rather than a constructed heap of material, a distinction that matters for understanding how much human labour went into the site and what the builders were doing with the landscape they found.
