Measuring just seven to eight metres across internally, the structure has accumulated at least two different names across the history of Ordnance Survey mapping: the OS Fair Plan labelled it a "Fort", while the second edition of the OS map recorded it as "Cloghaun", a term derived from the Irish word for a small stone structure or stony place. Neither name quite settles the question of what this enclosure originally was or what it was used for.

The enclosing bank is earthen in construction, ranging from two to four metres in width and rising somewhere between forty centimetres and one and a half metres in height, measurements that suggest a structure built for definition rather than defence. What gives it a particular texture is the revetment: at irregular intervals, upright slabs and stones set on edge have been worked into the bank to reinforce or face it. This technique of intermittent stone revetment is found across a range of early Irish enclosures, where it served to stabilise earthen banks on sloping or uneven ground. The site sits within the wider Corca Dhuibhne landscape of the Dingle Peninsula, a part of west Kerry exceptionally dense with early medieval and prehistoric field monuments, and was documented as part of J. Cuppage's 1986 archaeological survey of that area.
