The most legible of these earthworks sits in what was once the deer park of the Cahir Guillamore demesne, a roughly penannular shape, meaning an almost-complete ring open on one side, measuring around 25 metres across and open to the east. It is one of several such enclosures clustered together, each representing a probable medieval house site within a much larger deserted settlement, a category of monument describing a place where a community once lived and farmed but eventually, for reasons now lost, simply stopped.

The site has drawn attention for well over a century. Writing in 1896, a commentator named Dowd recorded local belief that the earthworks were the foundations of extensive buildings, with some going so far as to call them the remains of an ancient city of great extent. That reading may have overstated things, but it captured something real about the scale of what is visible here. The more methodical work came in 1942, when archaeologists Ó Ríordáin and Hunt examined aerial photographs of the area and identified the main earthwork, labelling it number 12 on their survey image and number 8 on an accompanying sketch plan. They noted additional circular or arc-shaped banks nearby, too indefinite for individual description but clearly part of the same complex, along with traces of a field system and further enclosures stretching to the east and north. The 1897 Ordnance Survey 25-inch map had already recorded the penannular shape, confirming that the earthwork was upstanding and recognisable well before aerial photography made the broader settlement legible.

The site lies around 45 metres west of a historic road or trackway, itself part of the same recorded landscape, and sits within grazing land rather than anything publicly managed or signposted. Orthoimages taken between 2005 and 2016, including via Google Earth, confirm the earthwork remains visible from above, which is often the clearest way to read it. At ground level, the banks are subtle and easier to appreciate in low winter light, when shadows pick out the curves of the earthwork against the surrounding pasture. Anyone approaching should bear in mind this is agricultural land, and the monument is best understood in the context of the wider deserted settlement around it rather than as a single isolated feature.
