The graveyard wall, which may incorporate traces of an earlier enclosure, surrounds the ruins of Kilrean church, a modest structure measuring 16 metres by 6.2 metres. Today, only the lower courses of its rubble-built walls remain, standing about a metre high, though various architectural fragments scattered about the site hint at its former glory. Among these pieces are a single-light window sill, a section of medieval hollow-chamfered hood-moulding, and two moulded sandstone voussoirs that once formed the round head of a window. The diagonal tooling on several sandstone blocks in the south wall and graveyard gateposts suggests a 12th-century date for at least some elements of the church.

The graveyard contains several intriguing cross-slabs that demonstrate the site’s long religious significance. The most impressive stands 1.57 metres tall south of the church’s southwest corner, featuring an elaborate ringed Latin cross on its western face with two concentric circles at its centre. Above and below the cross are distinctive square designs composed of interlocking triangles arranged in a swastika-like pattern; a common motif in early Christian art that predates its later, more sinister associations. Two other cross-slabs can be found within the enclosure: one bearing faint traces of a worn cross, and another near the western side displaying a plain Latin cross that may be of more recent origin.

Beyond the graveyard walls, the site reveals additional features that speak to its importance as a religious centre. A mysterious V-shaped stone structure, now covered in grass, sits in a field to the southwest, its walls forming an enclosure 8.5 metres long with an open northern end. To the southeast, a holy well continues the site’s sacred associations, whilst an erratic boulder or rock outcrop to the east bears a carved basin, 36 centimetres in diameter and 14 centimetres deep, likely used for ritual purposes. These various elements, scattered across the marshy ground, paint a picture of a site that served as a focal point for worship and community gathering for centuries, from the medieval period through to more recent times.
