The site is enclosed by an earthen bank that reaches up to 1.15 metres in height, though this defensive feature has been interrupted in the northeast quadrant where a later field wall now cuts through the ancient structure. The southwest side tells a more complex story, with evidence of stone revetment work and possibly the remains of a stone wall that once topped the earthen bank, suggesting various phases of construction and modification over time.

The interior of the enclosure remains largely flat, save for an intriguing arc of earthen bank, 1.9 metres wide, tucked into the angle where the field wall meets the original structure in the northeast sector. On the exterior slope of the bank, towards the south;southwest, archaeologists have identified evidence of a well, hinting at the practical needs of those who once occupied or used this site. Whilst a 1973 report mentioned traces of a collapsed souterrain; an underground passage or chamber typical of early medieval Ireland; these features could not be confirmed during subsequent surveys.

The setting itself speaks to careful site selection by its builders. Positioned on higher ground amidst a landscape of marshy lowlands and a patchwork of good and rough grazing land, the location would have offered both strategic advantages and practical benefits. This type of circular earthwork, often called a rath or ringfort, was a common feature of the Irish landscape from the early medieval period, serving as defended farmsteads for prosperous families. The site forms part of the rich archaeological heritage documented in the Archaeological Survey of County Donegal, compiled by Brian Lacey and colleagues in 1983.
