It follows a gentle, deliberate curve through otherwise unremarkable flat farmland near Clooncrippa, and the reason for that curve has been there far longer than the road itself. The bend exists to respect the arc of an ancient ringfort, a circular earthwork enclosure whose presence quietly shaped the landscape around it across many centuries, and continues to do so today.

A ringfort, or rath, is a type of enclosed settlement typical of early medieval Ireland, usually consisting of a raised earthen bank and an outer ditch, known as a fosse, constructed to define and defend a farmstead or small community. The example at Clooncrippa sits in level pasture and measures approximately 40 metres in diameter. Its earthen bank survives to an internal height of around 0.35 metres and an external height of 1.2 metres, with an external fosse roughly 0.9 metres deep and 1.2 metres wide. Compiled by Denis Power and uploaded to the record in August 2011, the site is one of countless such features scattered across Irish farmland, many of which have been levelled by agricultural improvement. This one has fared somewhat better, though not without modification. Along the eastern to southern arc, the fosse has been deepened and absorbed into the surrounding field drainage system, making it functional in a practical sense while obscuring its original character.

The interior of the enclosure is under open pasture at its centre, which makes the circular form legible enough from the right vantage point, but the perimeter and the enclosing bank are heavily overgrown with dense vegetation. The most telling feature for a visitor may actually be the road itself, which curves in a wide arc along the north-western to north-eastern side of the site, tracing the enclosure's edge as clearly as any surviving earthwork. Walking or driving slowly along that stretch, the deliberate geometry of the curve becomes apparent once you know what to look for. The site is not signposted or managed as a visitor destination, and access to the interior would depend on the landowner's permission, but the outline of the rath is largely readable from the roadside, particularly in winter when vegetation is thinner.
