At Termon in County Clare, an enclosure measuring roughly 40 metres north to south and 36 metres east to west survives as little more than a low earthen swell in the landscape, its wall reduced to an interior height of around 20 centimetres and an exterior height of about half a metre. Only where stones push through the surface does the original boundary become legible. The site went unrecorded on the ground for years; it was aerial photography in 2015 that finally made the oval shape visible from above.

The Burren is karst country, a terrain shaped by dissolved limestone where the rock surface is fractured into slabs and fissures known as clints and grykes. The interior of this enclosure reflects that geology directly: the ground is uneven, broken by limestone pavement close to the surface and scattered loose rock, making it difficult to read as a managed or occupied space. What gives the site additional interest is a small cairn-like feature, roughly 3.2 metres by 2 metres and about 55 centimetres high, built up on the south-eastern section of the enclosing wall. Cairns of this kind are accumulations of stone that can serve many purposes across different periods, from burial markers to boundary indicators, and their relationship to enclosure walls is rarely straightforward. Keegan, writing in 2016, noted several other cairns in the vicinity, suggesting this is not an isolated feature but part of a wider pattern of activity across the shelf. A second enclosure lies approximately 25 metres to the west, which raises the possibility that the two structures were related in function or period, though what that relationship was remains unclear.

The site sits on a level limestone shelf with open views east to west across the Burren, a quality that would have made it conspicuous and useful in any number of historical contexts. The collapsed and sod-covered state of the wall means there is little to see at ground level without knowing where to look, but the cairn feature at the south-east, sitting visibly on top of the enclosing elements, gives the eye something to fix on and a sense of the original wall's line.
