Whatever structure once occupied this ground has long since been levelled, yet a circular outline roughly twenty-three metres across persists in the pasture, defined by a low scarp, essentially a slight change in ground level, that runs around most of its circumference. At just over a third of a metre in height and around eight metres wide, this earthwork is less a wall or bank than a whisper of one, the kind of feature that rewards a careful eye rather than a casual glance. The eastern edge fades out almost entirely, leaving that quadrant of the circle unresolved.

Enclosures of this type, broad circular areas defined by earthen banks or ditches, are among the most common early medieval monuments in Ireland, often associated with settlement or agricultural use, though without excavation it is rarely possible to say precisely what purpose any individual example served. The name Rathclarish itself is suggestive, as the element "rath" in Irish placenames typically refers to a ringfort, a type of enclosed farmstead common across the country from roughly the fifth to the twelfth century. Whether this earthwork is the remains of such a settlement, or something earlier or later, the landscape at least preserves a trace of deliberate human organisation. The surrounding terrain is hilly upland, the pasture described as reclaiming, meaning vegetation is gradually reasserting itself over formerly worked ground, which itself says something about how land use in this part of Tipperary has shifted over time.
