This one, a roughly circular earthwork in reclaimed pasture in County Limerick, exists primarily as a ghost in the grass. It has never appeared on Ordnance Survey historic maps, and at ground level there is little to suggest anything is there at all. What archaeologists have instead are cropmarks, the subtle variations in vegetation growth that betray buried features beneath the soil, revealing a circular outline approximately 32 metres in diameter that only becomes legible from the air.

The site sits around 115 metres northwest of the ruins of Gormanstown Castle, with a second enclosure lying immediately to its southwest, suggesting this corner of County Limerick may have held a cluster of activity whose full character is still being pieced together. The earthwork first came to attention through a Bruff aerial photographic survey carried out in 1986, catalogued as Bruff 110, which flagged it as a possible enclosure. An enclosure, in this context, typically refers to a defined area bounded by a bank, ditch, or wall, the kind of feature associated with early settlement, agriculture, or ritual use across the Irish landscape. Subsequent orthophotography, including imagery from Ordnance Survey Ireland taken between 2005 and 2012 and a Digital Globe capture from 2011 to 2013, has offered partial confirmation of the outline, though the cropmark is intersected at its southwestern edge by a field drain running northwest to southeast. A further faint trace appeared on a Google Earth image dated 14 September 2019, with drainage ditches visible to the northwest and southeast. The record was compiled by Martin Fitzpatrick and uploaded in May 2021.

Because the monument is not visible on the ground in any conventional sense, visiting requires a degree of patience and the right conditions. Cropmarks of this kind are most legible during dry summer spells, when differential moisture retention causes the grass or crops above buried features to grow at a slightly different rate than the surrounding field. The site lies in working agricultural land, so access would require landowner permission. The ruins of Gormanstown Castle nearby offer a more tangible point of reference, and taken together, the castle, the enclosure to the southwest, and this ghostly circle in the pasture begin to sketch the outline of a landscape that rewarded closer attention long before anyone thought to photograph it from above.
