It appears on all editions of the Ordnance Survey map as a circular enclosure, a consistent presence across successive surveys, yet when you stand in the field today there is nothing to see. The site has been levelled entirely, leaving no visible surface traces.

A ringfort, to give it its proper context, is a roughly circular enclosure defined by an earthen bank and ditch, typically dating from the early medieval period and used as a farmstead or place of settlement. Thousands survive across Ireland in varying states of preservation, but many have been lost to agricultural improvement over the centuries, ploughed out or levelled when the land was cleared and put to pasture. At Carrowhall, local tradition has retained the memory of the site as a ringfort, which suggests it was recognisable within living memory even as the physical evidence was disappearing. That the Ordnance Survey cartographers recorded it consistently across multiple map editions means its outline can at least be traced on paper, even if the ground itself offers no confirmation.
