Measuring roughly 18 metres north to south and 21 metres east to west, it is defined by a low stony bank, barely 30 centimetres high on the interior side and even less on the exterior. What makes it quietly puzzling is how little it now registers on the landscape, given that it occupies a position with clear sightlines in every direction, the kind of elevated, open ground that was rarely chosen by accident.

The enclosure's most revealing appearance is not in person but on paper. The first edition Ordnance Survey six-inch map, produced in Ireland during the mid-nineteenth century as part of one of the most detailed cartographic surveys of its time, shows the feature as a circular wooded area approximately 20 metres in diameter. That the trees are now gone, and the bank so low as to be easily overlooked, suggests considerable change over the intervening century and a half. A largely demolished field wall runs along the eastern side, and there is evidence of small-scale quarrying and dumping within the enclosure itself, activity that has further disturbed whatever original character the interior once held. Whether the enclosure predates the field wall, or was built in relation to it, is not clear from what survives.
