The one at Coollick, in County Kerry, does neither. It sits on a gentle south-facing slope, partly under improved meadow to the north and rough ungrazed pasture to the south, and it is the kind of feature that rewards patience rather than spectacle. What marks it out is a quiet stubbornness: the enclosure has managed to survive, in some form, despite centuries of agricultural reworking, a bisecting field boundary, and the indifference of every map-maker who passed this way.

The enclosure is oval in plan, measuring roughly 24 metres north to south and 18 metres east to west. It is defined by a scarp, a low earthen edge or step in the ground rather than a built wall, running from east around through south to west at a width of about four metres and a height of around 0.8 metres. From west around through north to east, that scarp has been levelled by cultivation or land improvement, yet it remains traceable on the ground. A mature hedge combined with a concrete post and wire fence now cuts across the enclosure along a roughly west-northwest to east-southeast axis, the kind of field boundary that in Kerry can be generations old or relatively recent. What makes the site genuinely puzzling is its absence from both historic mapping and modern aerial photography, including surveys from 2010 and 2015. Enclosures of this type, whether early medieval ringforts or earlier pastoral boundaries, tend to leave at least a ghost on old Ordnance Survey sheets or to show as a cropmark or soil discolouration from the air. This one has left neither.
