A rath, as this type of site is commonly known, is a roughly circular earthwork enclosure formed by one or more banks and ditches, built primarily during the early medieval period and used as a defended farmstead or high-status residence. What gives this example its mild peculiarity is the asymmetry of its bank: noticeably wider and more substantial at the southwest, where it reaches 5.5 metres across, than at the northeast, where it narrows to 3.4 metres. Whether that reflects deliberate construction priorities, differential erosion over many centuries, or simply the practical constraints of the ridge on which it sits is not immediately obvious.

The fort occupies an east-west ridge in what is now pastureland, and its raised circular platform measures roughly 26.5 metres across. The bank itself survives to an internal height of between 0.6 and 1 metre, rising to 1.6 metres on the exterior, which suggests a structure once capable of providing a meaningful degree of enclosure. A poorly defined gap of about 3.5 metres in the bank at the southeast is interpreted as the probable original entrance, the point through which people and livestock would have passed during the lifetime of whoever built and occupied this place, likely somewhere in the period between the fifth and twelfth centuries.
