This is a rath, the Irish term for an earthen ringfort, a type of enclosed farmstead built predominantly during the Early Medieval period, roughly between the fifth and twelfth centuries. Tens of thousands of them once dotted the Irish countryside, and a great many survive in some form, but this one carries a particular quiet interest in the engineering choices forced upon its builders by the terrain.

The enclosure measures about 25 metres across its east-west axis and is defined by an earthen bank that still stands around 0.8 metres above the interior ground level, though animal activity has worn it considerably over time. Between this inner bank and an outer one, a fosse, meaning a defensive or boundary ditch, runs from the north-east around to the south-south-east. The outer bank, of the same height, continues from the north-east to the south-east before surviving only as a low scarp around the remainder of its circuit. Two breaks in the bank, one to the north-north-east at roughly 2.2 metres wide and another to the south-south-east, likely indicate original entrance points. What gives the site a subtle complexity is what the builders did on the western side: because the hillslope drops away in that direction, they raised the interior ground level and left a slight internal scarp running concentric with the outer bank, essentially levelling the living space against the pull of the gradient. The southern edge of the site sits above a steep drop down to the Funshion, which would have offered both a natural defensive advantage and a reliable water source. Much of the interior is now partially overgrown with bushes and briars.
