It does not announce itself to a passing walker. There is no visible mound, no ring of stones, no obvious break in the field surface. What gives it away is the grass itself, which, under the right conditions, betrays what lies beneath through subtle differences in growth and colour known as cropmarks. These are the faint signatures of buried ditches and banks, where soil disturbance from ancient construction continues to affect moisture retention and root depth long after the structures themselves have disappeared from view.

The site came to formal attention through an oblique aerial photograph taken on 23 August 2000, catalogued as ASIAP 118 (25), which captured the cropmark of a roughly circular earthwork on the reclaimed ground. Subsequent analysis of Ordnance Survey Ireland orthoimagery and a Digital Globe orthophoto taken between 2011 and 2013 allowed researchers to define the structure more clearly. The inner area has a diameter of approximately 20 metres and appears to be defined by a fosse, which is a term for a ditch typically cut as part of an enclosure or defensive boundary. Around this sits an outer ditch, bringing the overall diameter of the enclosure to roughly 75 metres. By February 2018, a Google Earth orthoimage showed the outer ditch still clearly legible from above. The record was compiled by Caimin O'Brien and uploaded to the national record in November 2021.

There is nothing to see at ground level in the conventional sense, which is precisely what makes the site interesting to anyone curious about how archaeology actually works in the Irish landscape. The location is on reclaimed grassland, meaning the terrain has been significantly altered over generations of agricultural improvement, and yet the earthwork persists as a coherent shape when viewed from altitude. The most practical way to appreciate the site is through the aerial and satellite images already in the public record, particularly the 2000 ASIAP photograph and the Google Earth imagery from 2018. If you do visit the general area, the surrounding Limerick countryside offers context for how thoroughly this kind of low-lying ground has been drained and reshaped over centuries, making the survival of any sub-surface signature all the more notable.
