A low scarp, no more than half a metre high, curves through pasture on a gentle rise, tracing the north-eastern to south-south-eastern arc of what was once a circular earthwork roughly 55 metres across. Everything else has gone.

A rath, to use the Irish term, was a roughly circular enclosure defined by an earthen bank and, typically, an outer ditch known as a fosse. They served as farmsteads during the early medieval period, from around the fifth to the twelfth century, and thousands survive across Ireland in varying states of preservation. The Listobit example was already in poor condition when a site report was compiled in 1976, which noted a raised circular area enclosed by a low bank of earth and stone. Even then, there was no trace of a fosse and the original entrance could not be identified. Since that report, the rath has been levelled entirely, and what little survives does so only because that north-eastern portion of the perimeter happened to be absorbed into a field boundary at some point, giving it a marginal degree of protection that the rest of the monument was not afforded.

The site sits in ordinary farmland, and what is visible now reads more as a slight unevenness in the ground than as any recognisable ancient form. Its interest lies less in what can be seen and more in what the partial survival suggests: that the field boundary which incidentally preserved this scrap of the circuit may well be older than the hedgerow or fence that currently runs along it, its line quietly inherited from an enclosure that predates it by more than a thousand years.
