When the Ordnance Survey first mapped this area in 1839, surveyors recorded it as an oval embanked enclosure, roughly 60 metres along its longer axis. By the 1924 edition of the same maps, it had been reduced to two east-west banks sitting inside field boundaries. The enclosure itself, however, had not changed; only the cartographers' interpretation of it had.

What survives on the ground today is a trapezoidal area, wider at its western end (around 55 metres) and narrowing to roughly 25 metres at the east, defined by earthen banks between about 5.8 and 6 metres wide. The banks stand noticeably higher when measured from outside, reaching 1.4 to 1.6 metres on their exterior faces, compared to just 0.5 to 0.8 metres internally. Paired with these banks on the north and south sides are flat-bottomed fosses, the term used for the ditches that typically accompany such earthen boundaries, each several metres wide. Unusually, neither a bank nor a fosse appears on the western or eastern sides of the enclosure, which raises questions about whether those boundaries were never built, have since eroded away entirely, or were always intended to be open. The ground falls away to the east toward a stream valley some 170 metres distant, so the eastern edge may simply have relied on natural topography as its boundary. Approximately 110 metres to the south lie the remains of Ballymaclare church and graveyard, a proximity that may be coincidental or may hint at a longer history of activity clustering in this corner of the landscape.
