While the rest of the field has been reclaimed and tilled over the years, this particular corner has been left alone, and what remains is a scarp just twenty-one metres long and no more than seventy centimetres high at its tallest point. Locally, the area is known as 'the lios', a word that in Irish tradition typically denotes a fairy fort or enclosed place, and that folk memory alone has kept the site's identity alive where the physical evidence has grown faint.

The earthwork is believed to be the remains of a rath, the most common type of early medieval Irish farmstead, usually consisting of a circular bank and ditch enclosing a domestic area. Most raths date from roughly the sixth to the twelfth centuries, though they continued in use for longer in some areas. What makes this particular example quietly arresting is not so much the earthwork itself, modest as it is, but what has accumulated within it. A children's burial ground sits inside the arc, the kind of site known in Ireland as a cillín, where unbaptised infants and others excluded from consecrated ground were interred, often over many centuries. The association between such burials and older, pre-Christian enclosures is well documented across the country; communities tended to place their marginal dead in places that already felt set apart. Roughly a hundred metres to the north-north-east, a possible souterrain has also been noted. Souterrains are underground stone-lined passages associated with early medieval settlement, used variously for storage, refuge, or ventilation of a dwelling above ground.

The site sits on a south-east-facing slope with a view down towards the mouth of Bantry Bay, a position typical of early farming settlements that favoured gentle slopes for drainage and aspect. The combination of a probable rath, a children's burial ground, and a possible souterrain within a short distance of one another suggests this corner of Cloghfune was in sustained use across a long period, even if the visible remains are now little more than a low grassy curve and a name preserved in local speech.
