This is a ring barrow, a prehistoric burial monument consisting of a roughly circular enclosed area defined by an earthen bank, with a shallow internal ditch, or fosse, running along part of its interior edge. The example at Park is modest in scale, measuring approximately twelve metres east to west and ten metres north to south, with a bank around 3.3 metres wide and barely a quarter of a metre high on the inside. These dimensions are typical of the type, which tends toward understatement rather than the dramatic mounded profile of a passage tomb or a large cairn.

Ring barrows are generally associated with the Bronze Age and Iron Age, and their distribution across Ireland suggests they served as funerary monuments, sometimes covering cremation deposits, sometimes acting as territorial or commemorative markers in the landscape. The one at Park retains faint traces of its internal fosse, visible in places along an east-north-east to south-west alignment, though boulders and smaller stones now clutter the southern half of the interior and the enclosing bank, obscuring what the original construction would have looked like. Trees and undergrowth have further softened the outline, so the earthwork presents itself less as an ancient monument than as a slight, grassy irregularity, the kind of thing that rewards a second look.
