The rath, roughly 37 metres in diameter, is defined by two banks with an intervening fosse, the term for the ditch dug between raised earthen walls that gave a ringfort its defensive profile. A field wall bisects it at two points, and to the south the monument has been levelled entirely. What remains visible is a stony patch in the pasture and a slight depression in the ground, the ghost of the fosse still readable if you know what you are looking for.

Ringforts of this kind were the standard unit of rural settlement in early medieval Ireland, typically enclosing a farmstead and its outbuildings, with the earthworks providing as much a statement of status as a physical barrier. Most were built and occupied between roughly the fifth and twelfth centuries. This particular example sits on a gentle rise in undulating pastureland, which is characteristic; a slight elevation would have improved drainage and visibility without requiring the effort of a hilltop site. What gives the Roxborough rath an additional layer of interest is its proximity to a second example of the same type, lying approximately 120 metres to the south-south-west. Paired or clustered ringforts are not unusual in the Irish landscape, and may reflect related family groups occupying adjacent land over the same period, though the relationship between any two such sites is rarely simple to establish.

The site sits in ordinary farming country, and its low profile means it blends readily into the surrounding fields. The stony ground and the faint linear dip where the fosse once ran are the clearest indicators on the ground. The second rath to the south-south-west, equally unassuming, is close enough that both can be taken in on a single walk across the area.
