The name Calluragh, used on those maps, typically denotes a children's burial ground or unconsecrated cemetery, a designation that would ordinarily carry its own quiet weight. Yet when the site was properly examined, there were no graves, no grave-markers, and no evidence that anyone had ever been interred there. The label, it seems, was simply wrong.

Known locally as Lissawalla, or Lios an Bhaile, the site is a rath, a type of circular earthwork enclosure built in early medieval Ireland, most commonly as a defended farmstead. It measures roughly 31.5 metres north to south and 33 metres east to west internally, enclosed by a single earthen bank and an outer ditch, or fosse. The bank is reinforced on its inner face with drystone masonry, a technique known as revetment, and there are traces of the same stonework collapsed at the outer base on the northern side. The northern arc of the fosse survives best, running 4.4 metres wide and close to a metre deep. To the south and south-east, a trackway has cut into and largely destroyed it. Two entrance gaps survive, one on the west measuring between two and three metres, one on the east at about two metres wide. A small clochaun, a dry-stone corbelled hut, was recorded inside the fort in the Ordnance Survey Name Books for Garfinny, though the banks and mounds now visible in the interior no longer resolve into any clearly identifiable structure. The archaeological survey of the Corca Dhuibhne area, published by J. Cuppage in 1986, provides the detailed account from which the site's modern description is largely drawn.
