Its circular outline is still legible, roughly forty-three metres across, but only just. The scarp, the slightly raised and scarped edge that originally defined the boundary of this rath, stands no higher than thirty-five centimetres in most places and drops even further at the south-southwest, where it has worn to around twenty-five centimetres. Without knowing what to look for, you could walk across it without registering that the ground beneath your feet had once been deliberately shaped.

A rath is the commonest type of ringfort found in Ireland, a circular enclosure defined by an earthen bank and a surrounding ditch, used primarily as a farmstead during the early medieval period, roughly between the fifth and twelfth centuries. The example at Rathreagh More follows the typical pattern: a roughly circular interior, here measuring approximately 42.8 metres north to south and 42.5 metres east to west, bounded by a scarped edge and an outer fosse, which is the term for the ditch dug to create the bank material. At this site the fosse is barely perceptible as you move from north to south, but it widens considerably at the north-northwest, reaching about seven metres across at its broadest point, suggesting that this section may have seen less disturbance or was originally more pronounced. The site was compiled and recorded by Denis Power, with notes uploaded in August 2011.

The interior is level and currently under grass, which makes the geometry of the site easier to read from a slight distance than from within it. A post-and-wire fence runs along a north-to-south axis through the interior, close to the eastern edge, a reminder that working farmland has long since absorbed the site into its daily rhythms. A farm trackway passes immediately outside the fosse to the north. Given how subtle the earthworks are, winter or early spring visits, when vegetation is lowest, offer the best chance of picking out the scarp and the faint line of the fosse. The widening of the ditch at the north-northwest is probably the most visually distinct feature remaining, and it is worth approaching from that direction to get a sense of what the original enclosure boundary would have looked like.
