It is not marked by dramatic earthworks or a commanding hilltop position, as many of its kind are, but by a modest raised bank and an encircling ditch that have survived, largely intact, in the middle of ordinary farmland.

The site is a rath, the most common form of ringfort found across Ireland, built during the early medieval period, roughly between the fifth and twelfth centuries. Ringforts served as enclosed farmsteads, the bank and fosse providing a degree of protection for a family, their livestock, and their dwelling. This particular example at Downs measures approximately 27 metres in diameter, a fairly typical scale for a single-family enclosure. The earthen bank stands to about half a metre on its inner face and a metre on the outer, while the fosse, a shallow external ditch running east to west, measures roughly three metres wide and 30 centimetres deep. The interior is level, suggesting the ground within was deliberately managed, though it is now partially covered by overgrowth. The site was recorded by Denis Power and uploaded to the national monuments record in August 2011.

The fort sits in open pasture, so access depends entirely on landowner permission, as is the case with the vast majority of field monuments in rural Ireland. There are no visitor facilities and no signage. What rewards the effort of finding it is the quiet legibility of the earthwork itself; even at these modest dimensions, the circularity of the bank is clear to the eye, and the relationship between the inner enclosure and the outer ditch gives a reasonable sense of how the original boundary would have functioned. Visiting in late winter or early spring, before the growing season thickens the overgrowth inside, offers the clearest view of the interior.
