It is roughly 12 metres across, defined by a low scarp no more than 40 centimetres high, its interior lumpy with grass-covered hummocks and ferns. Locally, people have always called it a tree-ring rather than a ringfort, and that distinction matters more than it might first appear. Ringforts, the circular earthwork enclosures found across Ireland in their thousands, were typically domestic settlements or farmsteads from the early medieval period. A tree-ring is something different: a circular earthwork planted with trees, usually designed as an ornamental feature within an estate or agricultural landscape. The function was aesthetic as much as practical, and the presence of two such features within 80 metres of each other at Loughananna suggests this was a deliberately composed piece of designed landscape rather than anything ancient or defensive.

The site sits on a gentle south-facing slope with open views stretching from the south-east to the west, which is precisely the kind of position a landscape designer would have chosen for a planted circular feature. A second tree-ring, recorded separately, survives in levelled form 80 metres to the north-west. Satellite imagery adds a quietly melancholy dimension to the record here. Google Earth orthoimages captured in October 2006 and again in November 2018 still show the outline of a tree-lined earthwork at this second location, its circular form legible from above. By September 2019, however, those surface remains had disappeared entirely. What was visible for over a decade had been levelled within a year. The site described here, the slightly raised circular area with its surviving scarp, appears to be a companion feature to that now-vanished earthwork, and may itself represent only partial survival. The record was compiled by Caimin O'Brien and uploaded in October 2021.

The site lies in open pasture, so access depends on landowner permission, as is standard for most archaeological features on private farmland in Ireland. There are no formal facilities or signage. For anyone who does make their way there, the thing to look for is subtle: a barely perceptible rise in the ground, a slightly circular outline in the turf, and the uneven texture of the interior where hummocks and ferns betray a disturbed sub-surface. Winter or early spring, when vegetation is low, gives the best chance of reading the earthwork's shape. It is the kind of feature that rewards patience and a slow walk around the perimeter rather than a glance from a gate.
