That height alone sets it apart. A ringfort, or rath, is a roughly circular enclosure built from an earthen bank, typically during the early medieval period, used as a farmstead or high-status residence. Many survive as low, eroded rings barely readable in the landscape. This one at Loughane is considerably more intact, its bank paired with an external fosse, a defensive ditch, that still drops to a depth of around two and a half metres and remains waterlogged along its eastern stretch.

The enclosure measures roughly 91 metres north to south and 90 metres east to west, making it a substantial example of its type. There are two gaps in the bank: a narrower one to the south-south-west, and a wider entrance to the east, around 4.8 metres across, with a causeway bridging the fosse. That causeway entrance has been damaged by machinery, which cut back the sides of the gap and left vertical sections through the bank exposed. A low stone-faced field boundary runs along the outer edge of the fosse. Writing in 1939, Hartnett noted a spring in the fosse to the south of the causewayed entrance, which may help explain why the eastern fosse remains waterlogged. Inside the enclosure, there is a possible souterrain, an underground passage or chamber often associated with storage or refuge in early medieval settlements. The interior was ploughed around 1984, which will have disturbed the uppermost archaeological deposits, though the surrounding earthworks remain largely legible.
