At the centre of the rath, a ringfort being a roughly circular earthwork enclosure used throughout early medieval Ireland as a farmstead or defended homestead, archaeologists have identified what appears to be a stone-built house site. It is oval in plan, measuring roughly 19 metres north to south and 22 metres east to west externally, with a bank about three metres wide. What makes it quietly puzzling is not its size but its placement: a structure apparently designed for habitation, positioned within an already enclosed space, with its own small depression measuring 4 metres by 3.5 metres cut into the north-western sector of its interior.

The ringfort itself carries a name that hints at something older: Lisnaweenoch, from the Irish Lios na Muimhneach, meaning roughly the ringfort of the Munstermen. That name suggests the site was associated with the people of the province of Munster, though at what point and under what precise circumstances the name attached itself to this particular enclosure is not recorded. The house site within it has no confirmed date; the archaeology places it inside the rath, but the relationship between the two structures, whether contemporary or sequential, remains unresolved. C. Toal documented the site in the 1995 North Kerry Archaeological Survey, and the physical evidence as recorded is straightforward: a stone bank, a measurable footprint, and that unexplained hollow in the north-west.
