The earthwork measures thirty metres across internally, with a bank rising to about 1.4 metres in height, stone-faced along its outer side. What makes it slightly odd, beyond its domestication into hedgerow and plantation, is an unidentified grouping of stones in the same field to the east, recorded separately and classified simply as anomalous, its purpose or origin apparently unresolved.

This is a rath, the everyday term in Irish archaeology for an earthen ringfort, a form of enclosed farmstead built and occupied predominantly during the early medieval period, roughly the fifth to twelfth centuries. Tens of thousands of them survive across Ireland in varying states of completeness, but each one sits within a specific local geography, and this example overlooks the valley of the Dripsey River, placing it within a landscape that would have offered both shelter and visibility. The entrance was noted as lying to the south-west by P. J. Hartnett, who recorded the site in 1939. That original observation remains the primary human detail attached to it: a researcher with a notebook, a direction of entry, and a date now more than eighty years gone.
