The enclosure is barely larger than a generous room, measuring roughly 4.8 metres by 4.55 metres, yet it carries considerable weight. It is one of five leabaí associated with the early ecclesiastical complex here, a leaba being a grave-plot or saint's bed, the kind of enclosed sacred space where proximity to a holy person's resting place was believed to carry spiritual significance.

The site appears on the Ordnance Survey six-inch maps under the name Aharla, though the scholar Tim Robinson, writing in 1980, recorded the enclosure as Leaba Bhreacáin, linking it directly to Saint Breacán, the early medieval figure to whom Teampall Bhreacáin is dedicated. The cluster of five such leabaí around the two churches, Teampall Bhreacáin and Teampall an Phoill, points to a place that once drew considerable devotional attention. High crosses of the kind whose remains now lie here were typically large, elaborately carved stone monuments, and the fact that the South Cross has been reduced to fragments adds a quiet melancholy to what is already a contemplative space. Gosling documented the site in 1993, placing it within a broader survey of the region's early Christian monuments.
