That asymmetry is part of what makes it worth attention. The eastern arc of the wall retains both its inner and outer stone facings, the drystone construction still legible after what may be well over a thousand years of weathering and agricultural use. The western arc is less fortunate, its facing surviving only in patches.

A cashel is a ringfort built from stone rather than earth and timber, a form particularly common across the west of Ireland where stone lay close to the surface and timber was scarce. This example is modest in scale, measuring roughly 41 metres from north to south and 36 metres from east to west, with a wall approximately three metres wide and surviving to just 0.6 metres in height. The discrepancy between the two halves of the monument is partly explained by what generations of farmers did with the stones they cleared from the surrounding fields. Loose rubble has been packed against the outer wall face on the south-eastern, southern, and western sides, the accumulated consequence of people tidying their land by dumping spoil against the most convenient nearby structure. It is a process that has simultaneously preserved and obscured, giving the monument an uneven profile that reflects centuries of working agriculture rather than any single dramatic event.
