The site, set in reclaimed farmland in Ballyculloo, County Galway, survives only in the layers of cartographic record and a single mid-twentieth-century description, all of which point to something that was already disappearing before anyone thought to look closely. Whatever once stood here has been absorbed entirely into the surrounding landscape, leaving no visible surface trace whatsoever.

The 1838 edition of the Ordnance Survey six-inch map recorded a roughly subcircular enclosure, approximately 40 metres across on its longer axis, of the kind loosely classified as a ringfort, or caher, a term used in the west of Ireland for a stone-walled enclosure that might have served as a defended farmstead in the early medieval period. By the time the area was resurveyed for the 1:2500 plan between 1912 and 1916, the outline had shifted in interpretation: hachures suggested something more subrectangular in plan. When McCaffrey examined the site in 1952, he found it 'very obscure' and identified a structure measuring roughly 12.5 by 7.3 metres, dimensions that seemed to him more consistent with a house site than a fort. Local knowledge agreed with this reading; the place was remembered simply as 'an old ruin of house'. McCaffrey also noted that a modern field wall cut across part of the monument, and pointed to a famine road built immediately to its north as the likely cause of most of the damage. Famine relief schemes of the 1840s produced hundreds of such roads across Connacht, often driven through or alongside older features with little regard for what lay beneath or beside them.

What makes the site quietly interesting is precisely this accumulation of uncertainty: a name beginning with caher that may never have been a caher, a shape that changed between surveys, a function that local memory reduced to the domestic and ordinary. The monument is, in the end, a record of erasure as much as of anything that once stood here.
