It sits on the crest of a ridge, the ground falling away to the north and east, and it would be entirely invisible were it not for the gap that opened up during tree removal works, when the roots gave way and revealed a large void beneath the surface.

A souterrain is an underground stone-built passage or chamber, typically constructed during the early medieval period in Ireland, and usually associated with nearby settlement activity. They were used variously for storage, refuge, or as escape routes. The one beneath this rectory garden belongs to the corbelled beehive type, where flat stones are laid in overlapping courses, each projecting a little further inward than the one below, until the roof closes into a dome without the need for any keystone or arch. Photographs taken through the opening, since direct access proved impossible, showed the chamber floor lying approximately 2.6 metres below the present ground surface, with a creep-way passage leading off to the north-north-west and a second opening to the south, partially blocked by collapse. The mortar holding the rough rubble boulders together is gravelly rather than lime-based, consistent with early construction methods. The site had clearly been disturbed before, with re-deposited soil and plastic sheeting found overlying the structure. Perhaps the most telling detail comes from Reverend Robert Deane, who recalled that when the rectory itself was being built in the 1970s, the building had to be repositioned to avoid the network of tunnels discovered running beneath the original proposed footprint.

The site is on private property within a rectory garden, so it is not accessible to the general public. The visible opening is small, roughly 0.9 metres across, and currently obscured by boulders and topsoil. Anyone with a serious research interest would need to approach through the appropriate heritage or ecclesiastical channels. The record was compiled by Margaret Keane and Christine Baker and uploaded to the national sites database in March 2017, making it at least formally documented, even if the chamber itself remains sealed and largely unknown.
