Roughly nine metres by thirteen metres in plan, and long since repurposed as an animal shelter, the structure belongs to a cluster of remains that together suggest this quiet hillside was once a more purposeful place.

The building first entered the formal archaeological record on the basis of a 1942 publication by Moran, which noted both the rectangular building and a nearby circular structure approximately ninety metres to the north-west of a mound and a cross-inscribed pillar. Cross-inscribed pillars are exactly what they sound like, upright stones bearing incised cross markings, and they appear widely across early Christian Ireland as simple devotional monuments. The rectangular building was already visible on the Ordnance Survey six-inch map of 1838, aligned on a north-east to south-west axis and shown as a roofed or at least intact structure. By the 1920 edition of the same map, it had been reduced to a three-sided outline, the cartographic shorthand for a ruin. Field inspection confirmed that what remains today is a vernacular building, the kind of plainly constructed domestic or agricultural structure, built from local materials without architectural pretension, that once formed the fabric of rural life across the west of Ireland. The company it keeps, a mound, a carved pillar, and a circular building, hints at a longer sequence of activity on this slope than the ruined walls alone would suggest.
