Most of what once defined it has vanished, leaving only a partial arc of earthen bank running from the east, around through the south, to the west-south-west. Beyond that surviving fragment, nothing breaks the surface. The enclosure's full circuit, which measured roughly 61 metres north to south, can now only be inferred rather than walked.

Enclosures of this broadly subcircular form are among the more common features of the Irish archaeological landscape, typically associated with early medieval settlement, although without excavation it is rarely possible to say much more than that. At Knockauns, even the partial evidence that remained has been further compromised over time. A field wall, built at some point after the monument fell out of use, cuts across the bank at the west-south-west. More significantly, quarrying activity has disturbed the south-western quadrant of the interior, removing whatever ground surface and potential deposits once lay there. A note from around 1975, attributed to a researcher named Knight, provides the earliest recorded description of what could still be observed at that time.

There is little here for a visitor in any conventional sense. The bank fragment that survives is the only physical trace, and even that requires knowing where to look across open bogland. The site is useful mainly as a reminder of how much of the archaeological record exists in a condition closer to absence than presence, its original shape recoverable only by measuring what little remains against what ought to be there.
