Most raths, the earthen enclosed settlements built across Ireland during the early medieval period, present a simple circular space within their bank and ditch. This one, sitting on a gentle rise in open pasture near Clonboy, carries something more unusual inside its perimeter: a Y-shaped bank that divides the interior into three distinct sections, crossing the centre on a north-south axis before splitting towards the south-east and south-west, leaving an enclosed residual area in the southern sector. Whatever its original purpose, that internal subdivision gives the site a structural complexity that sets it apart from the hundreds of plainer examples scattered across the Irish midlands.

When surveyors recorded the monument in 1971, they found a roughly circular enclosure measuring approximately 63 metres north to south and 59 metres east to west, its earthen bank still well-defined despite occasional disturbance gaps. The fosse, the external ditch that would have reinforced the bank's defensive or boundary function, survives around the perimeter, though a modern drain has been cut into its base at some point, and the outer face of the bank appears to have been deliberately steepened. A stretch of the bank along the south-eastern to south-south-western arc has been absorbed into a modern field fence, one of the more common fates of earthworks in agricultural landscapes. No original entrance can now be identified. The site was placed under a Preservation Order in April 1984, offering it a degree of formal protection against further alteration.
