The reality is rather more ornamental. What survives is almost certainly a tree-ring, a deliberately planted circular grove of trees enclosed within a low stone-faced bank, a feature associated not with prehistory but with the designed landscapes of Irish country estates. It is the sort of detail that can look prehistoric from the air and quietly domestic up close.

When surveyors examined the site, they found a large, roughly circular area measuring approximately 38 metres north to south and 36 metres east to west, enclosed by an earth and stone bank with a stone face, around 1.8 metres wide and 0.35 metres high. Trees have been planted both along the perimeter and throughout the interior, which slopes noticeably from west to east. The bank itself is irregular, curving in some stretches and meeting at right-angles in others, which gives the whole structure a slightly improvised quality rather than the precision of a formal garden feature. Oblique aerial photographs taken in 2001 still show it clearly as a coherent enclosure from above. The site sits in a slight valley among low rises of rough, outcropping land, with traces of limestone quarrying nearby, and a large house visible roughly 220 metres to the south-southwest. That proximity to a substantial residence is a telling detail; tree-rings of this kind were typically planted as landscape ornaments on estate grounds, serving as visual punctuation in an otherwise open or agricultural setting, sometimes sheltering game birds, sometimes simply marking ownership of the land in a genteel, arboricultural way.
