Somewhere beneath the ground in this part of County Galway lies the remnant of a souterrain, an underground passage or chamber typically cut from rock or built with dry stone, used in early medieval Ireland for storage or refuge. By the time archaeologist Wheeler recorded it in 1970, almost nothing remained: a short length of rock-cut tunnel, a single surviving roofing stone, and even that was inaccessible. No visible trace survives at the surface today.

The souterrain sits within what may be a cashel, a type of stone-walled enclosure used to define and defend an early medieval farmstead. The word "possible" carries weight in this context; the enclosure itself is uncertain enough that it warrants cautious classification, which makes the souterrain doubly elusive, a fragmentary feature within a structure whose own identity remains unconfirmed. McCaffrey had noted the site as early as 1952, placing it among a catalogue of similar features in the region, and Wheeler's brief description nearly two decades later added little beyond confirmation that the passage had been largely lost by then. What survives is less an archaeological site than an archaeological fact, something that existed, was partially recorded, and has since retreated entirely below the surface or into the ground itself.
