The one at Rockstown in County Limerick is different. It is almost perfectly square, measuring roughly 29 metres north to south and 29 metres east to west, enclosed within a stone wall built sometime after 1700. That regularity is unusual enough to make you stop and look again.

The site is recorded under the name Ballynacarrig or Rockstown Church, and the ruins of that church occupy the north-east corner of the enclosure. The relationship between the two is worth noting: the church came first, and the square graveyard grew up around and beyond it, eventually formalised by the post-1700 boundary wall. A bawn is a walled enclosure associated with a fortified house, but the term points to a broader tradition of deliberate enclosure in the Irish landscape; here, the walled graveyard serves a comparable function, drawing a firm line between the ground of the dead and everything outside it. The record was compiled by archaeologist Caimin O'Brien and uploaded to the national monuments database in January 2019.

The site sits in County Limerick, and like many small rural graveyards in the region it is likely accessible on foot from a nearby road, though visitors should expect the usual considerations of uneven ground and modest signage. The church ruins occupying the north-east quadrant are worth examining closely, as the junction between the older fabric of the building and the later enclosing wall often tells its own quiet story about how a site changed hands, changed purpose, or simply changed over time. The near-perfect geometry of the whole enclosure is best appreciated from the perimeter, where the uniformity of the wall makes the intention behind the layout feel deliberate rather than accidental.
