A large rectangular earthwork, measuring roughly 82 metres north to south and 67 metres east to west, survives here as a banked enclosure, its eastern side interrupted by a wide gap some 45 metres across. That break in the bank is the kind of detail that invites questions: an original entrance, a later collapse, a deliberate removal? The Ordnance Survey captured the whole thing on its 25-inch mapping in 1892, by which point the structure was already old enough to read as earthwork rather than standing architecture.

The site is associated with Beal Castle, and a 1943 account by Quinlan described the rampart surrounding the ruins as still being of considerable strength at that time, estimating the castle had been roughly 160 feet in diameter during its occupation. That figure sits interestingly against the mapped dimensions, suggesting a substantial enclosed complex rather than a simple tower. A bawn, the term for a walled or embanked enclosure attached to or surrounding a castle, was a common feature of Irish tower-house settlements, providing a defended yard for livestock and household activity. Whether this earthwork represents such a bawn, or an earlier or later phase of enclosure, is not clearly resolved, but the scale alone sets it apart from the more modest ringforts that dot the wider landscape.
