It measures about 119 metres north to south and 29 metres east to west, and at first glance there is little to distinguish it from the ordinary contours of a working field. What sets it apart is what local tradition says happened here: a battle between the warring tribes of Galway and Roscommon, after which the dead were buried somewhere within or around the enclosure. No trace of those burials is visible at the surface today.

Enclosures of this kind, defined by a single earthen bank, appear throughout Ireland and belong to a broad category of earthwork whose function can vary considerably, from farmstead boundaries to ceremonial or assembly sites. This particular example is classed as poorly preserved, meaning the bank has been worn down or disturbed to the point where its original form is difficult to read. The precise date of its construction is unknown, and no excavation appears to have been carried out to test the local battle tradition against the archaeology beneath the soil. The story of a territorial conflict between Galway and Roscommon factions is plausible enough as a piece of border folklore; the River Suck runs along the county boundary between the two, and the area would have been contested ground for various Connacht dynasties over the medieval centuries. But the tradition remains unverified, and the field keeps its silence.
