What survives of this ringfort is a flat oval platform at the summit, the faint footprint of an enclosure that once commanded clear views in every direction. Local information holds that the earthwork was levelled sometime in the mid-1960s, an era when agricultural improvement schemes across Ireland erased thousands of similar sites with little ceremony and less record.

A ringfort, sometimes called a rath, was a roughly circular enclosure defined by one or more earthen banks and ditches, used across early medieval Ireland as a farmstead and place of security. They are among the most common archaeological monument types in the country, with tens of thousands once dotting the landscape. This particular example was still visible and coherent enough in 1837 to be recorded on the Ordnance Survey Fair Plan of that year, where it appears as a circular earthwork annotated simply as "fort". That early survey provides the clearest evidence of what once stood here. A second ringfort survives approximately 150 metres to the east-northeast, making it possible to get a sense, in that neighbouring monument, of what the Knockatee site might once have looked like before the banks were pushed flat.
