Built from drystone, a technique requiring no mortar, relying instead on the careful stacking and interlocking of stones, it measures between 2.2 and 2.4 metres in diameter and survives to a height of roughly 0.9 metres. It is, by any reckoning, a modest thing. Whether it ever sheltered a person, or merely kept an animal out of the Atlantic wind, remains uncertain.

The structure was recorded as part of the 1986 Dingle Peninsula archaeological survey compiled by J. Cuppage under the title 'Corca Dhuibhne', a landmark study of one of Ireland's most archaeologically dense landscapes. The Dingle Peninsula has long been understood as unusually rich in early remains, from promontory forts and ogham stones to beehive huts and early Christian enclosures, and Knockmoylemore sits within that broader field of evidence. A circular drystone foundation of this scale could represent any number of things: a shepherd's temporary shelter, a small outbuilding associated with upland grazing, or even the remnant of something older. The survey entry does not commit to a date or a function, and that ambiguity is itself telling. Structures like this one, too small and too unelaborated to carry obvious meaning, often slip past the categories that archaeology finds most comfortable.
