This ring-barrow in the townland of Cross, in the barony of Coonagh, County Limerick, was not identified by anyone walking the land but by someone studying the sky above it. A ring-barrow is, broadly speaking, a circular earthen burial mound enclosed by a ditch or bank, a form of funerary monument common across prehistoric Ireland. This particular example is so faint that it appears as little more than a ghostly circular cropmark when seen from above, the kind of trace that only becomes legible when drought or differential soil conditions cause vegetation to grow unevenly over buried features beneath.

The site was identified during the Bruff aerial photographic survey in 1986, recorded as Bruff 106(4), reference AP 4/3676. The survey caught what was interpreted as a small circular cropmark consistent with a ring-barrow. Subsequent orthophotography by Ordnance Survey Ireland, taken between 2005 and 2012, still showed a faint trace of the monument, but by the time a Google Earth image was captured on 18 November 2018, even that had disappeared from view. The barrow sits on a north-facing slope in pasture, 92 metres southeast of the Reask River, which marks the townland boundary with Brackyle, and 123 metres east of the boundary with Knockballyfookeen. It is not an isolated find; it sits at the eastern edge of a cluster of five ring-barrows, and within 250 metres to the southeast lie three further barrows, an enclosure, and an earthwork. A possible enclosure has also been recorded 70 metres to the northeast. The record was compiled by Fiona Rooney and uploaded to the national monument database in July 2020.

There is little to see at ground level, which is perhaps the point. The surrounding pasture holds no obvious surface expression of the monument, and access would require landowner permission as the site sits on private farmland. For those interested in aerial archaeology or the archaeology of the invisible, the Bruff survey image remains the most direct way to engage with this site. The broader landscape context is what rewards attention: this corner of County Limerick preserves a concentration of prehistoric funerary and enclosure monuments that, taken together, suggest a once-significant ritual landscape, even if most of it now lies below the grass.
