This monument is described by Stout (1991, 271-4) as:
This monument, shown on the OS 6-inch map as a circular field fence, is located on the shoulder of a broad rise due north of the River Boyne. The underlying bedrock is Early Palaeozoic shale, covered by glacial deposits on which brown earth soil has formed. A probable passage tomb (ME025-006----) was located Broadboyne Bridge, 3.2km to the south-sout-east (Eogan 1974). A continuous flat-topped bank encloses a roughly circular saucer-shaped interior with an overall diameter of 110m. The source for the bank material was, presumably, this scarped central area. The bank is uniformly preserved and has an average height of 2.5m and width of 16m. A narrow ridge of earth, added to the outer lip of the bank top, probably dates from the conversion of the enclosure into a tree ring when the outer slope of the bank was steepened. A 6m-wide lowering in the bank in the south-west (269 degrees T) does not penetrate to the base of the enclosing earthwork and is unlikely to be original.
