This one in Glenlary, County Limerick, asks considerably more of the observer. Sitting in reclaimed pasture just ten metres west of the townland boundary with Cloghast, it does not appear on any Ordnance Survey Ireland historic maps, which means that generations of cartographers either missed it entirely or found nothing there worth recording. What survives today is so flattened that it reads more clearly from the air than from the ground, a circular mark in the grass that only makes sense when you know what you are looking at.

The site is classified as a possible levelled bivallate earthwork, meaning it would originally have consisted of two concentric banks and ditches enclosing a central area, a form of monument associated broadly with prehistoric and early medieval activity in Ireland. At roughly fifteen metres in diameter, it was never a large structure. An oblique aerial photograph taken on 5 January 2003, catalogued under reference ASIAP (342) 2, shows the earthwork intersected at its northern edge by a field boundary running east to west, which has cut across and further disturbed whatever remained of the original form. Later satellite imagery tells a similar story: Digital Globe orthoimages taken between 2011 and 2013, and a Google Earth image dated 26 April 2015, both show a circular area defined by a fosse, that is a ditch, with a surviving outer bank visible from the north-east to the south-east arc of the circuit. By August 2021, a further Google Earth image captures it only as a faint cropmark, the kind of ghostly discolouration in vegetation that appears during dry summers when buried features affect how plants draw moisture from the soil. The record was compiled by Martin Fitzpatrick and uploaded in October 2021. A related enclosure sits approximately one hundred metres to the north.

There is no visitor infrastructure here, and the site lies on private agricultural land, so any approach would require landowner permission. For those with an interest in landscape archaeology rather than monumental ruins, the more practical way to examine this one is through the aerial and satellite sources referenced in the official record. The cropmark is most likely to show clearly in late summer during a dry spell, when the difference between disturbed and undisturbed subsoil becomes legible through the grass above it. It is the kind of place that rewards patience with remote imagery more readily than it rewards a walk across a field.
