The earthwork in question was a rath, the Irish term for a ringfort, which is a roughly circular enclosure defined by one or more earthen banks and ditches. Ringforts were built across Ireland during the early medieval period, typically as enclosed farmsteads, and they survive in their thousands. This one, however, did not survive the late 1950s, when it was levelled, leaving behind only a faint arc of raised ground along its southern edge and a scattering of bushes growing where the enclosure once stood.

Before it was cleared, the site was recorded on two separate Ordnance Survey maps, and the differences between those records are quietly telling. The 1842 six-inch map shows it as a hachured oval enclosure measuring roughly 30 metres by 20 metres; by the time the 1937 six-inch map was produced, the same feature was depicted as a hachured circular raised area with a diameter of around 20 metres. Whether the discrepancy reflects genuine physical change to the site between those dates, or simply a difference in surveying approach, is difficult to say now. What local memory preserved, at least, was the low earthen rise that once enclosed the circular interior, and the field name that acknowledged what was there long before any map was drawn.

Visiting today, there is little to see beyond the pastoral landscape itself. The southern arc of raised ground is the most tangible remnant, and the cluster of bushes marks the general footprint of the enclosure. Field names in Ireland often outlast the monuments that inspired them, and "the fort field" is a good example of that quiet persistence.
