On the western side, the two overlap, the recent stonework sitting on top of a much-collapsed drystone enclosure that predates it by perhaps a thousand years or more. It is the kind of accidental layering that happens when people keep farming the same ground across generations, with little thought for what lies beneath.

What survives is a cashel, a type of stone-walled ringfort once used as an enclosed farmstead during the early medieval period in Ireland, roughly the fifth to the twelfth centuries. Unlike earthen ringforts, cashels were built from drystone construction, without mortar, relying on careful stacking to hold their form. This one is subcircular in plan, measuring 38.35 metres on its north to south axis, and sits beside a small stream in an area of scrubland. The wall that once defined it has largely fallen, leaving only a fragmentary outline, and where the western arc should close, a later field boundary has been built directly on top of it, obscuring whatever remained there.
