It lies within the interior of a rath, a type of circular earthen enclosure built during the early medieval period as a farmstead or settlement boundary, and it has left almost nothing visible to mark what it once was. A few stones are scattered along the south-eastern bank of that enclosure, and they may, or may not, be displaced grave-markers. That uncertainty is itself part of the picture.

Places of this kind are known in Irish as cillíní, informal burial grounds used for centuries to inter unbaptised infants, as well as others who were excluded from consecrated ground by church law. Their association with raths was not unusual; the earthworks of earlier, pre-Christian occupation carried a certain liminality in the popular imagination, making them appropriate places for those on the margins of religious community. The Cahercrin site is referenced in sources going back to Redington in 1916, and again in O'Flanagan's 1927 survey and in McCaffrey's 1952 work, suggesting it was known locally across generations. None of those sources describe anything elaborate; the site appears to have been modest from the beginning, and time has reduced it further.

What makes Cahercrin quietly telling is the completeness of its disappearance. The rath itself survives, but the burial ground within it has been absorbed almost entirely back into the ground, leaving only that tentative scatter of stones to suggest something more deliberate once took place here.
