The graveyard is a notably regular, almost square enclosure, measuring roughly 48 metres north to south and 52 metres east to west, the kind of deliberate proportions that suggest the boundary was laid out with some care rather than simply following the natural contour of the land.

The stone wall enclosing the site dates from after 1700, making it a relatively late addition compared to the church fabric it surrounds. The ruins themselves carry the monument record number LI021-008001-, and they sit in the western quadrant of the enclosure, which is a not uncommon arrangement in Irish ecclesiastical sites where an older church structure became gradually absorbed into a working burial ground as the surrounding community continued to use the land for interment long after regular worship ceased. The entrance gate is positioned at the south-east, orienting arrivals diagonally across the space towards the ruins. The site was recorded by Caimin O'Brien and aerial photographs were taken in March 2006 as part of the Archaeological Survey of Ireland.

Drehidtarsna is a small townland in County Limerick, and the site does not have the kind of signage or visitor infrastructure that draws crowds. The graveyard remains in use, or at least in care, so the enclosing wall and gate are generally accessible. The ruins in the western quadrant are modest, and the interest lies less in any dramatic surviving masonry than in reading the relationship between the post-1700 boundary wall, the older church footprint, and the continuing use of the ground around them. An aerial view, such as those taken for the Archaeological Survey, makes the square geometry of the enclosure far more legible than it appears from ground level, so it is worth seeking out the survey photographs before visiting.
