By the time someone came to inspect it in November 1955, it had already faded considerably; an Office of Public Works correspondent described finding only a low bank of indeterminate shape running close to a lane along the river's eastern bank. Not long after that, it disappeared from the ground entirely, levelled during Land Project works, the mid-twentieth-century state-backed drainage and improvement schemes that reshaped huge areas of Irish farmland, often at the cost of older earthworks that had quietly survived for centuries.

The enclosure first appears on the first edition Ordnance Survey six-inch map, published in 1839, and was still shown on the 1900 revision, which suggests it remained a recognisable feature of the landscape across at least six decades of mapping. Circular enclosures of this kind are common across Ireland, most often associated with early medieval settlement, the type sometimes called a ringfort or rath, a defended or enclosed farmstead defined by one or more earthen banks and ditches. The outer ditch, or fosse, is the element that has proved most durable here, not as a physical feature you could walk up to and examine, but as a cropmark visible on satellite imagery. Cropmarks appear when buried features affect how plants grow above them, with filled-in ditches often retaining more moisture and producing slightly lusher or differently timed growth that becomes legible from the air under the right conditions. That faint signature in the soil is now the only direct trace of what was once a substantial earthwork beside the Munster River.
