The souterrain, an underground stone-lined tunnel of the kind built during the early medieval period, possibly for storage or refuge, is now inaccessible; part of the hut floor above it has already collapsed into the passage, sealing the connection between the two structures in a way that feels less like ruin and more like slow digestion.

The site as a whole is a rath, a type of circular earthen enclosure that served as a farmstead in early medieval Ireland, typically enclosed by a bank and ditch to define and defend a household's space. This one sits in a large pasture field and measures roughly thirty metres across internally. It has not fared especially well. The southern and western sections of the enclosing bank have been reduced to little more than a low scarp, disturbed by cattle and obscured by dense vegetation; any trace of a fosse, the ditch that would originally have ringed the outside of the bank, has been effectively erased. Where the bank does survive, it reaches about 1.1 metres in external height and 1.4 metres at its base. A gap of 4.4 metres on the south side may mark the original entrance. Inside, towards the centre, stands the remains of a subcircular drystone hut, its walls still reaching 1.2 metres at the western side. A gap on the east, about 1.1 metres wide, likely served as its doorway. The names recorded for this townland offer two possibilities for what this site was once called: Lisnabobacky, from the Irish Lios na Bó Bacaí, and Lissacappagh, from Lios na Ceapaí. Either could refer to this enclosure, and the ambiguity has never been resolved.
