A caher is a type of stone ringfort, a roughly circular enclosure built from dry-stone walling, common across early medieval Ireland and typically associated with farming settlements of that period. At Lisleibane, the remnants of these huts occupy the central area and the south-western quadrant of the caher, their low wall footings still tracing the lives that once played out inside them.

The better-preserved of the two huts measures four metres across internally, with a 1.5-metre entrance gap opening to the east. Its wall footings survive to a height of around 0.8 metres and a width of 2.5 metres, substantial enough to suggest the original structure had some solidity to it. What adds an extra layer of interest to the site is a local tradition that a souterrain lies somewhere beneath or nearby. A souterrain is an underground passage or chamber, usually constructed from stone and roofed with large slabs, often built in association with ringforts as a place of storage or, in times of threat, concealment. The presence of one here, if confirmed, would deepen the picture of a settlement that was not simply a farmstead but a small, carefully organised world with its practical and defensive arrangements built in. The archaeological survey of the Iveragh Peninsula, compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996, recorded the site, though the souterrain remains a matter of local reputation rather than excavated fact.
