The site is known locally as Frot, a name that offers no obvious explanation, and the feature itself is the kind of thing that rewards a careful eye rather than a casual glance. What survives is a roughly circular area, measuring approximately 47 metres across, defined not by a dramatic bank and ditch but by a low scarp, a slight step in the ground where the enclosure edge was once built up. At its best-preserved stretch, along the western and north-western arc, that scarp is about two metres wide and one metre high, modest enough to be dismissed as a field boundary by anyone not looking for it.

A rath of this kind, an enclosed farmstead of early medieval Ireland typically surrounded by one or more earthen banks, was already old enough by 1834 to be marked on the first Ordnance Survey six-inch map with gothic lettering and the label "fort", the standard cartographic shorthand of the period for such ancient enclosures. The original external diameter was recorded at around 50 metres, and the earthwork sits on a rise near the crest of an east-west ridge, a position that would have given its original inhabitants a commanding view northward across the landscape. The site's more recent history is readable in the ground too. In 1968 a field bank was cut across the rath, bisecting it on a roughly north-north-east to south-south-west line. That bank was gone again by 1995, leaving the enclosure to recover something closer to its earlier form, though the northern arc has been absorbed into a road bank and is no longer fully distinct.
