The stones are the last visible trace of a cashel, a type of stone-built ringfort enclosed by a dry-stone wall, that once formed part of a much larger complex of monuments clustered around the townland boundary between Cahirguillamore and Rockbarton. The fort is not marked on any Ordnance Survey historic maps, which means it slipped through the documentary record almost entirely, surviving only as a faint earthwork on an aerial photograph and as a row of dressed stone half-buried in a yard.

The site came to scholarly attention in 1942, when archaeologists Seán P. Ó Ríordáin and John Hunt recorded it as Fort 1 in their survey of the area, noting the squared stonework visible in the farmyard and suggesting it continued beneath the house itself. They were documenting a landscape already deeply layered: the cashel sits within the southern quadrant of a relict field system, and within the boundaries of a deserted medieval settlement. Some fifty metres to the north-north-west stood Cahirguillamore Castle, itself now reduced to a site reference on the record. The whole cluster of monuments occupies what was once the eastern edge of the deer park belonging to Cahir Guillamore demesne, a detail that adds another historical layer to ground already crowded with the traces of earlier occupation.

There is no public monument to visit here in any conventional sense. A modern house and garden now occupy the site, and the levelled earthwork that Ó Ríordáin and Hunt recorded has long since disappeared beneath domestic life. What remains is more of an invisible geography than a physical one; a place that rewards looking at maps and aerial images rather than walking the ground. The 1942 survey, the annotated six-inch Ordnance Survey sheet, and a Google Earth orthoimage from March 2016 are among the few ways of getting any purchase on what once stood here. The squared stones visible in that farmyard are the sole physical thread connecting the present surface to the structure below.
