The site is a rath, the most common type of ringfort found across Ireland, typically consisting of a roughly circular area enclosed by one or more earthen banks and ditches. They date broadly from the early medieval period, roughly 500 to 1000 AD, and served as enclosed farmsteads for families of varying social rank. This particular example measures approximately 40 metres in diameter, a modest but not unusual size, and its defining bank is legible enough that it was recorded on the Ordnance Survey's 25-inch map series, produced in Ireland during the late nineteenth century.

What makes the site quietly notable is its situation within a wider local cluster of enclosures. A second ringfort lies roughly 60 metres to the south-east, suggesting that this part of Parsonstown was a settled, perhaps prosperous, farming landscape during the early medieval centuries. Paired or closely spaced ringforts are not uncommon in the Irish midlands, and their proximity can reflect family groupings, successive generations building adjacent enclosures, or simply the enduring attractiveness of particular patches of well-drained ground. The Westmeath example carries no documentary record in the physical archive for Irish field monuments, and much of what can be said about it comes from cartographic and remote-sensing sources, including aerial imagery captured between 2011 and 2013, in which the circular outline remains discernible beneath the grass.
