What looks at first like an ordinary field boundary is, on closer inspection, the remains of a cashel, the Irish term for a ringfort built from stone rather than the more common earth and timber. Its outer wall survives as a grass-covered spread of stone roughly two metres wide, with one or two courses of horizontally laid stonework still legible above ground, reaching between twenty centimetres and sixty centimetres in height. The interior face is flush with the ground inside, suggesting the original wall was substantial enough to have an appreciable thickness, now mostly collapsed and spread.

The site sits within what appears to be a multiperiod field system, meaning the landscape around it carries the accumulated marks of farming activity across several different eras, none easily separated from the others. By the time the Ordnance Survey produced its twenty-five inch maps in 1897, the cashel had already been absorbed into the working agricultural landscape; the survey depicts it as a curving field boundary, and shows a sheepfold built against the inner wall-face at the north-west. This layering is characteristic of early Irish enclosed settlements, which were frequently reused or modified long after their original purpose was forgotten. At some later point, a drystone wall between one and one-and-a-half metres high was constructed directly on the line of the outer wall-face, effectively borrowing the ancient structure as a foundation. Two further enclosures lie close by, one immediately to the south-west and another roughly eighty-four metres to the south-south-west, suggesting this part of the plateau was once a more densely organised settlement landscape than its present quietness implies. The cashel itself measures approximately 27.8 metres in external diameter, a respectable size for a site of this type.
