The ground rises only slightly, a broad earthen lip no more than about ninety centimetres at its highest, encircling a roughly circular patch of grass some thirty metres across. Yet that unassuming swell in the earth is the remnant of a univallate rath, the most common type of enclosed farmstead from early medieval Ireland, built by a single earthen bank rather than the concentric rings found at more elaborate sites. This one has been heavily levelled over time and is, as the landscape itself seems to admit, barely distinguishable from the field around it.

The rath measures approximately 33.3 metres north to south and 30 metres east to west internally, with a bank around 5.8 metres wide. It sits to the south of Tobernahornah holy well, a proximity that is unlikely to be coincidental; raths and holy wells frequently occupy the same intimate corners of the Irish countryside, each accumulating its own layer of local significance across different periods. To the west, Rahoneen Castle is clearly visible, placing this quietly eroded enclosure within a landscape that was, at various points, both settled and defended. The castle and the rath are not contemporaneous in any straightforward sense, but together they give the surrounding fields a depth that the flattened earthwork alone would not suggest.

The site sits in a field corner, which partly explains its survival, however diminished. Field corners have long served as informal repositories for things that could not easily be ploughed away or built over. A visitor who knows what to look for will find the low, wide bank running in a broad arc, more felt underfoot than seen from a distance, with the holy well a short way to the north offering a clearer landmark to orient by.
