The feature is subcircular, stretching roughly 56 metres north to south and 54 metres east to west, and at its centre is a raised area of around 20 metres in diameter. Around that rise, traces of two low banks and three shallow fosses survive, a fosse being a ditch cut into the ground as part of an enclosing arrangement. What makes the site quietly puzzling is precisely what it is not: despite its general shape, the low-lying, waterlogged setting argues against it being a ringfort, the kind of enclosed farmstead that dots the Irish countryside in the thousands, typically built on higher, drier ground for both practical and social reasons.

With the ringfort explanation set aside, attention shifts to Lisduff House, which stands to the north-northeast. The enclosure may have functioned as a designed landscape feature connected to that property, the sort of earthwork that Georgian and Victorian landowners occasionally commissioned to give their grounds a sense of antiquity or formal structure. The surviving evidence is fragmentary. The inner fosse, inner bank, and middle fosse are most legible on the southeastern to southwestern arc, while the outer bank can be traced from northeast to southwest. Elsewhere, a natural or artificial scarp takes the place of a constructed bank. The outer fosse holds its shape from the southeast around to the west-southwest. A cluster of trees has taken root along the outer bank, which has both preserved and obscured the underlying form.
