Located 420 metres from the Coolnamohoge townland boundary, this rectangular earthwork wasn’t recorded on the earliest Ordnance Survey maps from 1840, but by 1897 it appeared as a distinct feature measuring roughly 29 metres northeast to southwest and 27 metres northwest to southeast. The site was originally enclosed by an earthen bank along its southern and southwestern sides, which had been incorporated into field boundaries to the north, east and southeast, whilst elsewhere the defences had eroded to mere scarps.

The site’s rediscovery came about through aerial photography taken in November 1984 during the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline survey, where it was identified as a potential moated site. These medieval earthworks, typically dating from the 13th to 14th centuries, were defensive homesteads surrounded by water-filled ditches; common features of the Anglo-Norman landscape in Ireland. For decades afterwards, the site remained visible on various aerial images as a sub-rectangular area marked out by trees, clearly distinguishable on orthoimages from 2006 through to 2013.

Unfortunately, the physical remains of this historic site have since vanished from the landscape. A local road running northeast to southwest had already truncated the western portion of the earthwork, and by 2018, Google Earth imagery showed that the remaining surface features had been completely levelled. What was once a tangible link to medieval settlement patterns in rural Limerick now exists only in historical records and old photographs, a reminder of how quickly our archaeological heritage can disappear without proper protection.
