It appears on the Ordnance Survey map of 1842, drawn as a circular enclosure in the landscape, and then it simply vanishes, absent from the revised edition published in 1916. No earthwork, no raised bank, no depression in the ground remains to mark where it once stood.

Ringforts, known in Irish as raths or cahers depending on their construction, were among the most common settlement types in early medieval Ireland, typically consisting of a circular area enclosed by one or more earthen banks and ditches, used to protect a farmstead and its livestock. Thousands survive across the country in varying states of preservation. This one in Caherulla does not. Whether it was levelled for agriculture, quarried for its material, or simply worn away over centuries is unrecorded. What the 1842 map captured was already, in some sense, its last reliable appearance. By the time surveyors returned, it was gone, and the landscape had closed over it entirely.
