It is the kind of feature that rewards patience and a good satellite connection rather than a drive down a country road, because this particular site was not found by a field surveyor walking the land but by someone studying aerial photographs on a computer screen.

A ring barrow is a burial monument, typically of Bronze Age date, consisting of a low central mound surrounded by a circular ditch and sometimes an outer bank. They are funerary features, places where the dead were interred beneath earthen mounds, and they occur across Ireland in varying states of preservation. This example at Knockatancashlane was identified by Denis Power, who spotted it in aerial imagery from Bing Maps and Google Earth and uploaded his findings in June 2013. What Power noticed was a possible ring barrow positioned in the south-western corner of a larger enclosure already recorded in the Sites and Monuments Record under the reference LI014-155001. The relationship between the two features, whether the barrow predates the enclosure or was deliberately placed within it, remains an open question. The identification is listed as tentative, a "possible" rather than a confirmed monument, which places it in a category of sites awaiting further ground investigation or more detailed remote sensing.

Because this site has been identified primarily through aerial observation rather than ground survey, visiting it in any conventional sense requires some preparation. The townland of Knockatancashlane is in County Limerick, and the enclosure within which the possible barrow sits can be located using the same aerial tools that brought it to attention in the first place. Cross-referencing the SMR number LI014-155001 through the National Monuments Service online mapping system will help pinpoint the location. Access to the field itself would require landowner permission. The feature is likely to be subtle at ground level, perhaps barely perceptible as a low earthwork, since ring barrows of this kind often survive only as slight undulations in pasture. That ambiguity is part of what makes it interesting, the site exists at the threshold between confirmed archaeology and informed suspicion.
