What makes it quietly unusual is not just its preservation but its topography: the northern side of the enclosure is defined not by a conventional bank but by a natural ravine dropping 4.5 metres, the site's builders evidently choosing to fold a dramatic geological feature into their defences rather than engineer everything from scratch.

A rath is an earthen ringfort, a type of enclosed farmstead built in early medieval Ireland, typically between the sixth and tenth centuries, and tens of thousands of them survive across the island in varying states of ruin. This one on Bentee follows the general pattern: a circular bank and fosse, the fosse being a flat-bottomed ditch roughly 1.2 metres wide and averaging 2.4 metres deep, with the bank itself composed of earth, gravel, and a substantial quantity of stone, falling some 2.7 metres to the ditch below. On most of the circuit the inner face of the bank rises only about half a metre above the interior ground level, a modest height by the time it is measured today. No formal entrance gap has been identified in the enclosure, though a possible causeway across the fosse appears at the south-east. Inside, a circular hut survives as a collapsed stone wall roughly 1.4 metres wide, enclosing an interior space of 5.8 metres in diameter, compact but functional. The site looks west across to Valentia Harbour, an outlook that would once have made it as practical a lookout point as a dwelling.

The ground around it is rough pasture, and the rath is described as densely overgrown, so what is visible from the outside is likely to be more suggestive than legible. The ravine on the northern side is probably the most dramatic feature a visitor would encounter, the earthworks elsewhere being relatively low and humbled by time.
