A souterrain is an underground stone-built passage or chamber, typically associated with early medieval settlement and used variously for storage, refuge, or ventilation. This one survives only as a mapped coordinate, its physical presence entirely swallowed by construction and daily use.

The souterrain was recorded within the northern interior of what is thought to be a rath, the circular earthwork enclosure that was the standard form of rural farmstead in early medieval Ireland. A school was later built to the south-west of the site, and the school yard now covers the ground where the souterrain once lay detectable. No surface trace remains. The rath itself carries a provisional classification, suggesting the earthwork too has been substantially obscured or degraded over time. What was once a functioning element of a living settlement has been quietly buried beneath the routines of another era entirely.
