The ruins sit at the heart of a roughly rectangular enclosure, approximately 34 metres from north to south and 54 metres from east to west, a modest but deliberate space that has continued to receive the dead long after the church that once defined it fell silent.

The ruins, recorded under the Sites and Monuments Register reference LI029-059001-, are medieval in origin, though the enclosing stone wall dates to after 1700, suggesting that the site was maintained and formalised well into the post-medieval period. An entrance gate at the southern end of the western wall marks the principal way in. By 1840, when the Ordnance Survey Letters recorded local observations across Ireland in remarkable detail, the site was described simply as "a small graveyard here much in use." That phrase, practical and unsentimental, tells its own story. The ruins had presumably been a ruin for some time, yet the ground around them remained a place where people continued to bury their dead, drawing on an older attachment to the site that no amount of architectural decay could dissolve.

Rathnaseer lies in County Limerick, and the graveyard is typical of what are sometimes called "old graveyard" sites in Ireland, where a medieval ecclesiastical foundation, often long since collapsed, continues to function as a burial ground for the surrounding community across many generations. Visitors approaching through the gate in the western wall will find the ruined church centrally placed, as the records describe. The site is modest in scale and unlikely to reward those seeking dramatic architecture, but for anyone interested in the layered relationship between medieval religious sites and the communities that outlasted them, the continuity here is plain to see in the headstones arranged around walls that no longer have a roof above them.
