The ring-barrow at Ballyholahan is modest almost to the point of invisibility: a circular area just four metres in diameter, defined by a scarped edge, a shallow fosse (the encircling ditch that is characteristic of the ring-barrow form), and an outer earthen bank so low it barely registers above the surrounding ground. A ring-barrow is broadly a round burial monument enclosed by a ditch and bank, a form used across Ireland and Britain during the Bronze Age, though examples vary considerably in scale and preservation. This one sits at the smaller and more subtle end of that spectrum.

What gives the site an added layer of interest is its relationship with a near-identical monument immediately to its south-southwest. The two ring-barrows share an outer bank, their earthworks running together so that the boundary of one becomes the boundary of the other. This kind of pairing suggests that whoever constructed them understood both monuments as part of the same funerary landscape, whether built at the same time or added in deliberate sequence. A cluster of other barrows lies nearby, reinforcing the sense that this unremarkable-looking field once served as a place of repeated, organised burial activity. The site was identified from Ordnance Survey aerial photography, reference 2430/29, which is itself a reminder of how much of Ireland's prehistoric archaeology remains legible only from the air, the ground having long since absorbed its contours into ordinary farmland.
