Cartographers noted a circular enclosure, a form of monument common across early medieval Ireland, where such ringworks typically enclosed a farmstead, a defended residence, or occasionally a ceremonial space. By the time anyone thought to document it in detail, the structure had been almost entirely levelled. What survives today is an oval-shaped mound measuring roughly 7.8 metres by 3 metres internally and standing just 0.6 metres high, a low swell in the ground that most people would walk past without a second glance.

The two OS map surveys, from 1841 to 1842 and again from 1914 to 1915, offer a quiet kind of evidence. They show that the enclosure was still recognisable as a distinct feature well into the twentieth century, which makes its subsequent near-disappearance all the more striking. The cause of that levelling is not recorded, though agricultural improvement and land clearance have reduced countless similar monuments across Kerry and the wider country. What the ground at Farrandeen now preserves is less a monument than a trace, the faint residue of something that once had a clear outline and presumably a clear purpose.
