According to local information recorded at the time, the fort had been levelled approximately a decade before the site was formally documented, leaving behind only low undulations in the pasture where the earthworks once stood. That the place still carries a formal archaeological designation is, in its own quiet way, a record of erasure as much as of survival.

Ringforts, known in Irish as raths when formed from earthen banks and ditches, were the most common form of enclosed farmstead in early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. Thousands survive across the country in varying states of preservation, but many have been lost to agricultural improvement, particularly during the twentieth century when land clearance accelerated. The Codrum example sat on ground overlooking the Sullane valley, a placement typical of these enclosures, which were often sited for drainage, visibility, and access to productive land. Its levelling reduced what would once have been a raised circular bank, perhaps accompanied by a fosse or outer ditch, to the faint swellings now barely legible in the grass.
