This oval enclosure at Kerries sits on just such a platform of exposed rock, and the position was clearly chosen with panoramic awareness in mind. Tralee Bay opens out to the south and west, the Stacks Mountains rise to the north-north-east, and the full spine of the Sliabh Mis range runs along the southern horizon. Most striking of all, the site offers a direct sightline to two cairns on the saddle below the summit of Knockawaddra Mountain to the south-east, those cairns marking the entrance to Scotia's Glen, a valley otherwise concealed behind the bulk of Knockmichael.

A ringfort, or rath, is a roughly circular or oval enclosure typically defined by an earthen bank and ditch, used as a defended farmstead during the early medieval period in Ireland, though some examples have prehistoric origins. What sets this particular fort apart is that its enclosing bank is built entirely of stone, with no evidence of a ditch on either side, the construction material apparently quarried from within the enclosure itself. That internal quarrying has left the interior with a distinctly bowl-shaped profile. The bank survives almost all the way round, reaching 1.7 metres in height on the northern side where the natural scarp of the reef adds to the effect, and up to 7.5 metres wide at its base on the north-eastern arc. A gap of around seven metres on the south-western side is thought to mark the position of the original entrance, though it has widened considerably over time. At the centre of the enclosure sits a large rubble mound, the collapsed remains of what appears to have been a substantial stone structure, oval or sub-circular in plan, with internal dimensions of roughly 10.8 metres north to south and 7.5 metres east to west. A short stretch of standing wall on the north-western side suggests original walls around 1.3 metres thick. A low linear stone bank running from the hut towards the probable entrance further hints at the internal organisation of the settlement. The analysis of this site forms part of Michael Connolly's 2008 doctoral thesis on prehistoric settlement in the Lee Valley hinterland of Tralee, undertaken at University College Cork.
