What makes this particular rath worth a second look is not its size, though at 46 metres across it is a respectable example of its type, but the souterrain tucked into its northern interior. A souterrain is an underground stone-built passage or chamber, typically associated with early medieval settlement, used for storage, refuge, or both. The presence of one here suggests the site was once a functioning domestic enclosure rather than a purely symbolic or defensive structure.

A rath is an earthen ringfort, a form of enclosed farmstead common across Ireland from roughly the sixth to the tenth centuries, though many were built and used outside those dates. This one was noted by Bowman in 1934, who recorded it as a single-ramparted fort in land belonging to E. MacSweeney, with a fosse, meaning an encircling ditch, of around fourteen feet in width. By Bowman's time that ditch was already described as practically filled in, and the bank itself has since become heavily overgrown. A two-metre-wide gap in the bank to the south-west is likely the original entrance, a common position for rath entrances and one that would have offered good visibility across the slope.
