That near-invisibility is itself the curious thing about this group of ring-barrows, a type of monument in which a low, flat circular platform is enclosed by a surrounding ditch, or fosse, and an outer earthen bank. They were typically used for burial during the Bronze Age, though the precise date and use of these three examples has not been established from the available records.

The site was documented by O'Kelly in 1944, who described all three as "exactly similar in diameter" and noted that the banks were slight while the fosses remained well defined. The diameters he recorded were 4.5 metres, 5.5 metres, and 7.3 metres respectively, making them modest but coherent examples of the form. Despite their existence being known to researchers, the monuments do not appear on Ordnance Survey Ireland historic mapping, and a possible ring-barrow at the site was separately catalogued by Grogan in 1989 under the designation "Ballynamona 6". The three monuments are recorded together in the national Sites and Monuments Record under the reference LI040-061007 through 009.

By the time aerial orthophotography was carried out between 2005 and 2012, no surface remains were visible whatsoever. The ground had been so thoroughly reclaimed for pasture that the monuments had effectively disappeared from view at ground level. What brought them back into focus was a Google Earth image captured on 14 September 2019, which showed a circular-shaped cropmark, the kind of faint discolouration in vegetation that occurs when buried ditches retain moisture differently from the surrounding soil, revealing the presence of something beneath. For anyone curious enough to visit the general area, there is little to see on the ground, and locating the precise spot without reference to the satellite imagery would be difficult. The site is best understood as an example of how much prehistoric landscape survives in Ireland not as visible earthwork but as information encoded in the soil, legible only under the right conditions of light, season, and drought.
