The site was recorded on the 1838 edition of the Ordnance Survey six-inch map as a subrectangular enclosure, meaning roughly rectangular but with slightly irregular sides, measuring approximately 56 metres on its northeast to southwest axis and around 47 metres north to south. When a field archaeologist visited in October 1982, no visible surface trace survived at all. The enclosure had not been destroyed so much as absorbed, folded quietly into the working landscape around it.

The maps tell a story of incremental erasure. By the time the 1921 Ordnance Survey edition was produced, a field boundary running northwest to southeast had cut directly across the site, leaving only the northern portion depicted. Other field boundaries had already overlaid the enclosing element along its southeast and southwest sides, meaning the enclosure's outline was being progressively redrawn as agricultural infrastructure rather than as an ancient feature in its own right. What the enclosure originally contained or when it was built is not recorded, but such subrectangular enclosures in the Irish landscape are broadly associated with early medieval settlement, sometimes enclosing a farmstead or small agricultural complex. The name Lissadulta itself carries the Irish word lios, referring to just such an enclosure, suggesting the feature was significant enough to anchor the place-name long after any physical trace had gone.

The site is now pastureland, and a visitor standing in the field would see nothing remarkable underfoot. The one remaining way to perceive the enclosure's outline is through aerial imagery, where slight traces are visible from roughly south through west to north, the ghostly arc of an edge that centuries of farming compressed but could not entirely remove.
