The site belongs to a category of monument that has all but dissolved back into the land, leaving only the faint memory of its own outline pressed into the soil.

A ringfort, sometimes called a rath, was a circular or oval enclosure typically built during the early medieval period, defined by one or more earthen banks and ditches, and used as a farmstead or place of habitation. This particular example in Garranekeagh was recorded on the Ordnance Survey Ireland six-inch map of 1840, where it was annotated as one of the "Knockannaskeagh forts", depicted alongside a companion enclosure immediately to the east, the two earthworks sitting either side of a field boundary. By the time the more detailed OSi 25-inch map was published in 1897, the monument had already been partially levelled, surviving only as a raised oval-shaped area roughly 20 metres in its longest dimension, defined by a low scarp running from the north-west around through the east and south. The possible second ringfort to the east is catalogued separately under reference LI047-075002. By the twenty-first century, the earthwork proper had effectively gone, but satellite imagery tells a different story: cropmark evidence captured on Digital Globe orthoimages taken between 2011 and 2013, and again on a Google Earth image dated 28 June 2018, reveals a roughly circular mark approximately 24 metres across in both the north-south and east-west directions, the buried archaeology influencing plant growth just enough to betray itself.

The site sits in pasture roughly 200 metres south of a roadway that forms the townland boundary with Tobernea East, so there is no meaningful structure left to observe at close quarters. The most informative view is through aerial or satellite imagery, where the cropmark is clearly legible during dry summers when differential soil moisture causes grass above buried features to stress and discolour at a different rate than the surrounding field. Anyone with a serious interest in the site would do well to consult the compiled orthoimages noted in the record, and to cross-reference with the neighbouring possible ringfort to the east, since the pairing of two enclosures so close together, as the 1840 mapmakers clearly recognised, is itself the more interesting detail here.
