What aerial photography and careful survey work have revealed is not the neat ceremonial ring that the name implies, but a roughly oval embanked enclosure, approximately 35 metres north to south and 45 metres east to west, with a bank nearly 11.5 metres wide and a central hollow partially surrounded by an irregular scatter of stones. It sits in pasture, quietly unremarked, within a landscape so dense with related monuments that the ground itself seems to have been continuously occupied and reoccupied across millennia.

The site does not appear at all on the Ordnance Survey six-inch map of 1840, which is itself telling. By the 1897 edition of the 25-inch OSi map, it had been annotated as a stone circle, a designation that has followed it ever since, including onto later Cassini editions. But the circular-enclosure form visible on Google Earth imagery from 2013, 2018, and 2020 fits a pattern that archaeologists have been reassessing in this part of Limerick. Excavations on the nearby Knockadoon Peninsula at Lough Gur, documented by Cleary in 2018, identified similar so-called stone circles as Late Bronze Age settlement enclosures, structures that surrounded domestic houses rather than serving any ceremonial function. Relic field boundaries, visible on orthoimages from 2005 to 2013, run across the monument to the north, south, east, and west, suggesting that later agricultural activity has cut through and partially obscured whatever the original form was. Within roughly 320 metres of this site there are at least three other monuments of the same general type, and St Patrick's Well, along with an associated church and graveyard, lies just 440 metres to the north.

The site sits on private farmland, so access would require the landowner's permission. Those approaching from the Patrickswell direction should be aware that the monument lies close to the townland boundary with Loughgur, roughly 195 metres to the east of that boundary. The north-facing slope gives good views northward, and the surrounding field system, though heavily modified, is still legible in places as low earthworks running across the pasture. Anyone with an interest in how archaeological categories can mislead, and in how a single label applied in the 1890s can shape how a place is understood for generations, will find this quietly complicated corner of Knockderc worth the attention.
