" That designation points to something older than the house, older than the townland boundary markers, older perhaps than most of what now surrounds it, yet there is nothing visible at ground level today to confirm it is there at all.

The enclosure sits north of the eastern limit of the estuary, tucked to the rear of Lissenhall House. Enclosures of this kind are broadly understood as circular or sub-circular earthworks, often the remains of a ringfort, which was a form of enclosed farmstead common across Ireland from the early medieval period roughly between 500 and 1200 AD. They were typically formed by one or more earthen banks and ditches, and served as a defended homestead for a farming family and their livestock. The 1837 OS six-inch map, Ireland's first systematic large-scale survey, was meticulous enough to record the site's presence even then, suggesting local knowledge of its significance had survived into the nineteenth century. Whether the feature was already reduced to near-invisibility by that point, or whether it has since been levelled by agriculture or development, is not recorded in the available sources. The record was compiled by Geraldine Stout and updated by Christine Baker.

Because the enclosure is not visible at ground level, a visit here is an exercise in reading landscape rather than observing monument. The estuary setting provides orientation; the site lies to the north of its eastern limit, behind Lissenhall House. Access to the immediate area would need to be confirmed before any visit, as the land is in private ownership. For those with an interest in historic mapping, comparing the 1837 OS six-inch sheet with the current landscape online using the OSI historical map viewer can give a clearer sense of where the feature once registered as significant enough to name.
