The site at Inchnanoon is easy to miss entirely: a subrectangular patch of earth, roughly 14 metres east to west and 9 metres north to south, set apart from its surroundings only by a low bank of earth and stone. At its centre stands a single grave marker, the sole visible evidence that this quiet enclosure was ever used to inter the dead.

Small enclosed burial grounds of this kind, set apart from churches and their associated graveyards, are not unusual in the Irish landscape, though they are frequently overlooked. They sometimes represent early medieval or later folk burial practice, where communities interred unbaptised children, strangers, or the socially marginalised in ground that lay outside consecrated parish cemeteries. The low earthen and stone bank that encircles the Inchnanoon site serves the same function as a more elaborate boundary wall might elsewhere, marking the threshold between ordinary agricultural land and ground given over to the dead. That only one grave marker now survives at the centre does not necessarily reflect how many people were buried here; many such sites have lost their markers to the slow erosion of centuries, or the markers were never cut from stone to begin with.
