The incident, recorded by Myler in 1998, is how this particular souterrain came to anyone's attention at all. There are no visible surface remains, no stones poking through the grass, no obvious indication that anything lies below. The site simply looks like a farmyard on a south-facing terrace above the valley of the Mealagh River, with Mullaghmesha rising across the way.

A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement in Ireland, often used for storage, refuge, or both. When local investigators looked into the Ardrah collapse in 1998, they described two chambers extending southward from the point where the truck had broken through. Beyond that brief examination, the structure has not been formally excavated or documented in any detail. What remains is essentially a void, its age and original purpose unconfirmed, sitting undisturbed beneath the everyday routines of a farm.
