The enclosure measures roughly 17 metres north to south and 16 metres east to west, bounded by an eroded earthen bank that rises no more than 0.4 metres above the surrounding ground. That modest height is part of what makes it quietly puzzling; whatever this bank once was, time and water have worn it down considerably.

Enclosures of this general type, circular earthen boundaries built to define or defend a space, appear across Ireland in various forms and from various periods, ranging from early medieval farmsteads to enclosures associated with ritual or agricultural use. The difficulty here is that the interior sits level with the floodplain and shows signs of regular flooding, which complicates any straightforward reading of the site. A deliberately settled or farmed enclosure would typically seek drier ground; the waterlogged conditions raise questions about whether the location was always this marshy, or whether the landscape has shifted around the structure over the centuries. No excavation record is noted, so the date and function remain open.
