A cashel is a ringfort built from stone rather than earth and timber, a form common in the west and south of Ireland where suitable fieldstone was plentiful and easily stacked into a defensive perimeter. Here, that perimeter has largely collapsed, but its outline survives as a roughly circular spread of tumbled masonry, measuring around 32 metres north to south and 35 metres east to west.

What makes the site more than a simple ruin is the evidence of how it was adapted long after its original purpose had faded. A later wall was added along the outer face of the cashel to the north and east, suggesting that someone, at some point well after the structure was built, found a practical use for the old enclosure boundary, perhaps as part of a field system or livestock management. Two gaps break the circuit of the wall, one to the east at roughly two metres wide and another to the west-north-west at around two and a half metres, which may represent original entranceways or later breaches. Inside the enclosure, the ground is crossed by cultivation ridges running on an east-north-east to west-south-west axis, the kind of lazy-bed pattern associated with spade-dug potato cultivation from the post-medieval period onward. The interior, in other words, was at some stage given over entirely to tillage, the prehistoric or early medieval domestic space converted into a working field.

The site lies in pasture today, which means the cultivation ridges within it are still legible at ground level, most visible in low raking light when the slight undulations of the old ridge-and-furrow pattern cast soft shadows across the grass.
