It is roughly circular, measuring about twenty metres north to south and seventeen metres east to west, and its flat top is rimmed by a scarp, the sloped edge of an earthen platform that still holds its shape after centuries of agricultural life pressing in around it. A gap in the scarp to the north hints at an original entrance, though a drain cut east to west across that side has clipped the monument and obscured whatever once lay there.

The antiquarian Thomas Johnson Westropp, writing between 1916 and 1919, noted it in his survey work, describing the feature as a flat-topped mound girt by a fosse, situated not far from Clogher Hill. A fosse is simply a ditch, typically dug to define or defend an enclosure, and Westropp's characterisation of it as a mote places it within a loose category of raised earthworks that appear across Ireland with varying origins, some medieval, some much older. The 1897 edition of the Ordnance Survey of Ireland twenty-five-inch map records it by name, which at least confirms the place had a recognised identity by the late nineteenth century, even if its precise age and function remained unspecified. The name Raheennamadra itself is worth pausing on: ráithín na madra in Irish, meaning something like the little ringfort of the dog or dogs, a small and slightly curious designation that offers no firm historical answers but adds a layer of local character.

The monument sits in working farmland, so access would require landowner permission. Its outline is heavily overgrown, and at ground level the platform can be easy to misjudge; the scarp is more legible from a slight distance or, as researchers have found, from aerial imagery. Visiting with the 1897 Ordnance Survey map as a reference helps to orient the eye toward what the earthwork once looked like when its edges were clearer. The surrounding pasture is flat enough that the mound, modest as it is, still registers as something deliberate in the landscape.
