That omission is part of what makes them interesting. The pair survived not through any formal recognition but simply by enduring in damp ground, quietly going about the business of being ancient while drainage channels and field boundaries were cut around them.

A ring barrow is a burial monument of prehistoric origin, typically consisting of a central mound or level platform surrounded by a fosse, which is a shallow ditch, and an outer bank of thrown-up earth. The Kildromin example was only identified as such during the Bruff aerial photographic survey of 1986, when the survey image labelled 289 (AP4/3633) revealed a small circular earthwork from the air that had gone unnoticed at ground level. Later orthoimagery, including an Aerial Survey Ireland photograph taken in October 2002 and more recent Google Earth imagery from September 2020, confirmed both the primary ring barrow and a second, slightly smaller companion conjoined to its south-east. The larger measures fourteen metres in diameter; its neighbour thirteen. Both share the same structural form, each defined by a fosse and enclosed by an outer bank. The site sits on low-lying wet pasture in the townland of Kildromin, County Limerick, about 150 metres east of a land drain and 360 metres north-west of the townland boundary with Ballinlough. Two other recorded monuments lie close by: an enclosure roughly 105 metres to the west, and a moated site, that is, a medieval platform surrounded by a water-filled ditch, approximately 140 metres to the south-south-west.

The ground here is genuinely wet, cut through with land drains and watercourses, and access across the pasture will depend on the season and recent rainfall. The earthworks are upstanding and visible to a careful eye on foot, though their modest height means they read more clearly from aerial imagery than from ground level. Anyone visiting should look for the slight rise and dip of bank and fosse forming two adjoining circles in the field, the conjoined geometry being the most distinctive feature of the site. The research was compiled by Alison McQueen and Vera Rahilly and uploaded to the record in November 2020.
