What makes it unusual is its shape: not the typical rounded dome one might expect, but a circular, saucer-shaped depression roughly 30 metres across, as though the earth has gently subsided rather than risen. This inverted quality gives it an odd, almost counterintuitive presence in the landscape, and it belongs to a class of prehistoric monuments known as barrows, earthen funerary structures that were used for burial across Ireland and Britain from the Neolithic through the Bronze Age.

The monument sits within an enclosing bank some 7 metres wide and 2 metres high, with an internal ditch measuring 10 metres across and half a metre deep, bringing the overall diameter of the whole complex to approximately 70 metres. That combination of an external bank and internal ditch is a defining feature of a particular barrow type, and it hints at the deliberate, labour-intensive planning that went into its construction, likely thousands of years ago. There are two breaks in the enclosing bank worth noting. In the north, a gap in the bank lines up with a causeway across the ditch, suggesting a formal entrance or approach route that was built into the original design. In the south-east, a second break corresponds with a waterlogged area, which may be the result of later ground disturbance or simply the low-lying nature of the terrain. These details were recorded by O'Kelly in 1942 and later compiled by Geraldine Stout.

The site sits in agricultural land, so access requires care and consideration for the working farm context. The low, saucer-shaped interior is easier to read from slightly elevated ground nearby, where the relationship between the bank, ditch, and central area becomes clearer. The waterlogged south-eastern section is worth approaching cautiously, particularly after wet weather, which in this part of Limerick is a reasonable year-round concern. The causeway in the north is the most legible feature at ground level, offering a sense of how the monument was once entered or circumnavigated.
