What makes this site unusual is not just its survival but what appears to be preserved inside it: a series of earthen ridges and a low circular mound that together suggest the ghostly footprint of domestic life within the enclosure's banks.

The site is classed as a univallate rath, meaning a roughly circular enclosure defended by a single earthen bank and an outer fosse, or ditch. Raths of this kind were the typical farmstead of early medieval Ireland, occupied roughly between the fifth and twelfth centuries, and tens of thousands of them once dotted the countryside. What distinguishes this example at Leath is the internal arrangement. Two earthen ridges, set 5.4 metres apart, extend eastward for 17.5 metres from the western part of the interior, terminating at a low circular mound measuring approximately 6 metres by 5.6 metres and standing just 0.6 metres high. From that mound, two further ridges run south for around 8 metres, eventually meeting the inner face of the south-eastern bank. The configuration is tentative in the archaeological record, described as possibly suggesting house-sites, but the geometry is suggestive: parallel ridges of that scale could represent the remains of structures whose walls or foundations have long since slumped into the soil. The site commands an extensive view of the surrounding countryside, which would have been a practical consideration for any early farming community alert to what was moving across their land.
