The remains measure roughly eight metres north to south and nine metres east to west, defined by the collapsed remnants of a drystone wall that now barely clears ankle height. Drystone construction relies on no mortar, the stones held together entirely by their own weight and careful placement, and when such walls fall, they tend to spread low and wide rather than topple in a single dramatic collapse. What survives here is a wall face that rises to perhaps thirty-five centimetres on the exterior, slightly less on the interior, and is around ninety centimetres thick. The interior is level, the setting open, and the views across the valley to the south and south-west are long and unobstructed.

The structure was identified from aerial photography in 2015, its circular plan legible from the air in a way that it may not be on the ground. Circular enclosures of this kind are a common feature of the Irish landscape and can date anywhere from the prehistoric period through to the early medieval, sometimes serving as settlement boundaries, sometimes as animal enclosures, and sometimes with purposes that remain unclear. What is clear at Termon is that the wall has suffered considerably over time. There are intermittent gaps where the enclosing material has been removed, and the most likely explanation is that the stones were repurposed to build the field wall that now runs along a north-west to south-east axis roughly a metre and a half to the north-east. This kind of quiet cannibalisation, one old structure feeding a more recent one, is a recurring pattern across the Irish countryside. Two thorn trees, which in Irish tradition often mark places of some significance, stand at the north and north-east edges of the enclosure.

The site sits in rough pasture on a karst landscape, the type of terrain formed from soluble limestone bedrock and characterised by thin soils, exposed rock, and occasional sinkholes. In the Burren region of Clare this kind of ground is widespread, and it tends to preserve ancient features simply because it has never been worth ploughing. The low wall is inconspicuous, and the gaps in it make the circuit hard to follow continuously, but the overall shape becomes legible once you are looking for it.
