The field above them is in tillage, the ground apparently ordinary, and to a passing eye there is no clue that anything lies beneath. That combination, a multiple-chambered souterrain under working agricultural land with no visible trace whatsoever, makes this a quietly anomalous site even by the standards of a county that has no shortage of buried archaeology.

A souterrain is an underground stone-built passage or series of chambers, typically associated with early medieval settlement in Ireland, often used for storage or as a place of refuge. They are frequently found in connection with ringforts, the circular enclosed farmsteads that dot the Irish countryside in their thousands. At Gorteenadrolane, the hillock is identified as the possible site of one such ringfort, though that enclosure too has left no surface trace. The information about the six chambers comes from local sources rather than formal excavation, which means the precise layout, construction, and condition of what lies below remains unverified. Whether the chambers are intact, partially collapsed, or accessible in any way is simply not known from the available record.
