A bivallate rath is a roughly circular enclosure defined by two concentric earthen banks and ditches, a form of enclosed settlement used throughout early medieval Ireland. What makes this one particularly interesting is not the banks themselves but what survives inside them: an extensive souterrain, which is an underground stone-lined passage or chamber typically associated with storage or refuge, and the scattered remnants of hut-sites preserved as spreads of stone and curving arcs of stony banks across the interior.

The evidence for the hut-sites is fragmentary enough that surveyors working from J. Cuppage's 1986 Dingle Peninsula archaeological survey were unable to determine how many structures once stood here, how they were arranged, or what their dimensions were. That ambiguity is itself telling. The site is densely overgrown, and the vegetation has effectively put the interior beyond easy reading. What can be said is that people lived within these banks, built structures whose footprints are now only faint curves of stone, and dug or constructed at least one underground passage into the ground beneath them, suggesting a settlement of some duration and organisation rather than a temporary camp.
