There is no mound, no hollow, no marker of any kind. The site has, as the record puts it plainly, no visible surface trace.

The chambers came to light in the early 1980s when a ringfort on the same land was levelled. Ringforts, roughly circular enclosures typically bounded by an earthen bank and ditch, were the dominant form of rural settlement in early medieval Ireland, and many contained souterrains, stone- or earth-cut passages and chambers built beneath the ground. Their exact purpose is still debated, though cold storage, refuge, and ventilation for adjacent structures have all been proposed. At Peafield, the souterrain consisted of two earth-cut chambers roofed with lintels, flat stones laid horizontally across the top of the passage walls. That much was recorded at the time of the ringfort's destruction. The enclosure that once protected and contextualised the souterrain is now gone, and with it any obvious reason for the ground to attract attention.
