The site is categorised as a souterrain, the term used for the dry-stone tunnels and chambers built beneath early medieval raths, typically used for storage, refuge, or both. This one is recorded, located, and almost entirely invisible.

The souterrain sits within a rath, a circular earthwork enclosure of the early medieval period, the kind that dots the Irish countryside in the thousands and is still frequently mistaken for a natural feature. In 1832, labourers cutting a small lane through the centre of the fort broke into what was described, when the discovery was written up in the 1840s, as a cavern. That lane still runs across the northern half of the rath on an east-west axis, and a waterlogged patch along its course is the closest thing to a marker the site now offers. No structural remains are visible above ground, and there is no indication that the interior was ever formally recorded or excavated after that initial, accidental exposure.
