Scattered through the churchyard of St. Cronán's, which now surrounds the Church of Ireland building, are carved limestone remnants that were never meant to end up here, set into a wall or balanced on top of a nineteenth-century altar tomb.

The site sits immediately east of St. Cronán's Romanesque church, one of the finest examples of twelfth-century Irish ecclesiastical architecture in the midlands. Romanesque churches of this period are distinguished by their richly ornamented doorways and arched openings, using a vocabulary of carved stone that was elaborate and deliberate. The graveyard has accumulated several fragments from that tradition, including three pieces of roll-moulded stone built into the southern boundary wall, one of which formed part of an arch. Even more striking are two loose pieces of limestone window tracery that were, at the time of inspection, resting on a nearby altar tomb. Tracery refers to the shaped stonework that fills the upper portion of a Gothic window, dividing the opening into decorative patterns. Both fragments still carry traces of concrete and lime mortar, suggesting they had been casually embedded in a wall at some point, perhaps when an older structure was being repaired or consolidated. One retains a glazing-bar hole, evidence that it once held glass in place. The other preserves glazing slots on both interior faces. Two cross-slabs have also been recorded within the graveyard, adding to the sense that the ground here has been accumulating carved stonework across many centuries.

Visitors to Roscrea who take time to walk the graveyard will find the altar tomb near the western wall, north of the Romanesque church. The fragments themselves are modest in size, the larger of the tracery pieces measuring just over forty centimetres in length, so they reward close attention rather than a passing glance. The roll-moulded stones in the southern wall are easier to miss, incorporated as they are into the fabric of the boundary itself.
