On the earlier map it was recorded as a circular univallate enclosure, meaning a single-ditched ringfort of the kind that once served as a farmstead or minor defended settlement across early medieval Ireland. By the time cartographers returned to revise the sheet, it had been reduced in description to a mound, its form softened by time and field boundaries. The transformation on paper reflects what had already happened on the ground.

The site sits near the foot of the eastern slopes of Lateevemore, on the western side of the broad valley through which the Milltown river runs southward to Dingle Harbour. What remains today is a densely overgrown earthen mound, roughly 26 metres across from east to west, rising on average about 1.5 metres above the surrounding fields. It is composed mainly of earth with some small stones, and its northern half is now partly defined by irregularly curving field fences rather than any clearly archaeological boundary. Around the southern base of the mound there is a possible fosse, the term for a defensive ditch typically dug around an enclosure of this kind. Here it survives only as a suggestion: a two-metre band of reeds and a shallow depression just a few centimetres deep, barely legible in the landscape. These details were recorded by J. Cuppage in the 1986 Dingle Peninsula archaeological survey, a systematic examination of the Corca Dhuibhne region that documented hundreds of sites across this archaeologically dense stretch of the Kerry coast.

The name Cathair Bó Sine adds another layer of quiet interest. Cathair in Irish generally refers to a stone fort or enclosure, though the structure here appears to be predominantly earthen. Whether the name preserves a memory of an earlier stone-built phase, or simply reflects a looser local usage of the term, is not clear. What the landscape around Lateevemore does make clear is that this particular valley has been settled and worked for a very long time, with the Milltown river below and the mountain slopes above framing a place that accumulated names, boundaries, and meanings long before any map was drawn.
