The current modern church stands just north of where an older church once stood; a substantial building that measured 52 feet by 21 feet with walls three feet thick and reaching up to 14 feet high, complete with a vaulted tower at its western end before it was pulled down in 1828. Whilst some have claimed traces of a circular enclosure survive here, recent surveys haven’t been able to confirm these remnants.

The real treasure of this site lies beneath the surface, where just south of the present church, a modern entrance leads down into an elaborate souterrain. This underground structure begins with a subcircular shaft that drops 1.8 metres before opening into a rectangular doorway that leads, via two steps, into a central chamber measuring 5.6 metres east to west. The chamber’s partially corbelled walls are closed with carefully placed slabstones, and doorways lead to both eastern and western chambers. Remarkably, one of the roof slabs in the eastern chamber is actually a re-used cross slab, its circular depression and groove design still visible despite centuries underground. The western chamber stretches 8.7 metres and may preserve evidence of the original entrance at its far end, where the roof stones step upwards and soil has accumulated beneath them.

Scattered throughout the graveyard are several notable cross slabs that speak to the site’s long Christian heritage. These include a graveslab near the church’s southeast corner bearing a Latin cross with distinctive bar terminals and an unusual H-motif at its base, and a broken cross slab found east of the church that displays intricate designs including a three-pointed star surrounded by L-shapes, triple interlaces, and a quartered circle motif all connected by a central stem. The collection of carved stones, ranging from crude incisions to elaborate interlace patterns, demonstrates the evolution of stone carving traditions at this prominent ecclesiastical site over many centuries.
