This possible bivallate enclosure, barely visible at ground level, shows up distinctly in aerial photographs as a pair of concentric circular cropmarks. The inner circle measures roughly 15 to 18 metres across, whilst an outer ring, separated by a gap of about 8 metres, spans approximately 35 metres in diameter. A linear cropmark, likely an old field boundary running northeast to southwest, cuts across the northwestern edge of the larger circle, suggesting the enclosure predates the later agricultural divisions of the land.

The site occupies level ground that gradually slopes about 50 metres southward into a stream valley below. Walking the field today, you’d struggle to make out much beyond faint undulations in the grass; the central circular area can just about be traced from southeast to northwest, and intermittent hints of the outer circle appear as slight rises in the ground at the southern, western and northwestern edges. The landscape holds other intriguing features too: 90 metres to the northwest stands an erratic boulder known locally as ‘Cloch na Crushlen’, marked on old Ordnance Survey maps, whilst about 100 metres north, woodland conceals an underground river passage where the roof has partially collapsed, exposing the water rushing through its rock-carved ravine.

Though its exact purpose and date remain uncertain, this double-ringed enclosure joins countless other earthworks across Ireland that hint at past settlements, ceremonial sites or defensive structures. The bivallate design, featuring two concentric boundaries, was a common feature in prehistoric and early medieval Ireland, used for everything from ringforts to ritual spaces. Its preservation as cropmarks rather than substantial earthworks suggests considerable age and centuries of agricultural activity that have gradually levelled the original banks and ditches, leaving only these ghostly outlines visible when conditions are just right.
