What makes the site quietly unusual is the layering of its remains: not just a single dwelling but at least two conjoined huts, and possibly a third, all contained within a univallate rath, that is, a roughly circular enclosure defined by a single earthen bank or wall. Raths are the most common type of early medieval farmstead in Ireland, built in their thousands between roughly the fifth and twelfth centuries, but most visitors to Kerry walk past their grassed-over outlines without ever registering what they are looking at. Here, the interior has not been swallowed entirely by the ground.

The enclosure at Killelton is oval in plan. Inside it, the pair of conjoined huts, two structures sharing a wall or built directly against one another, have collapsed into a low spread of loose stone. A further spread of stones to the east of these may indicate a third structure, though the evidence is uncertain enough that it warrants only a cautious reading. The site was documented as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published in 1986 under the editorship of J. Cuppage, a systematic effort to record the extraordinary density of archaeological monuments across this part of County Kerry. The conjoined arrangement of the huts is of some interest; paired or clustered structures within a rath interior are not unknown, but they hint at the organisation of daily life, perhaps separate spaces for sleeping, storage, or animals, within what was essentially a single farmstead.
