The structure is roughly subcircular, measuring about 33 metres east to west and 31 metres north to south, its perimeter marked by a wall so thoroughly grassed over that it reads now more as a gentle undulation in the field than as a built thing.

What makes this particular cashel worth a second look is a detail at its west-south-west side, where the wall bulges outward around a gap nearly nine metres wide. That outward projection is thought to be original, suggesting this was the designed entrance rather than a later breach. Cashels of this kind are generally associated with the early medieval period in Ireland, roughly the fifth to the twelfth centuries, when enclosed stone ringforts were a common form of rural settlement across the west of the country. The monument has not escaped the slow reorganisation of the landscape around it; a later field wall cuts straight across the interior, running from the north-north-east down to the south, slicing through the older enclosure with the indifference of a much later agricultural logic.
