It measures just under twelve metres across, and its bank of stone and earth has long since collapsed and greened over, yet it retains a surprisingly legible outline: a roughly circular form with two deliberate gaps, one facing east-south-east and one west-north-west, suggesting original entrances rather than simple erosion.

The enclosure appears on the Ordnance Survey six-inch maps of both 1840 and 1916, marked with hachures, the cartographic convention used to indicate an earthwork or raised feature. That it was recorded across two separate surveys, more than seventy years apart, suggests it was at least visible enough to warrant notation, even as the land around it gradually reverted to marsh and rough pasture. Its bank stands between 0.6 and 0.8 metres high, slightly taller on the north side, and varies between two and six metres in width. Along the southern edge, where the ground falls sharply toward the river, the bank definition deteriorates, eroded by the steepness of the slope. The site sits roughly 155 metres west-south-west of Smithstown Castle, a tower house whose presence nearby hints at a landscape that was once more actively managed and inhabited than its current condition would suggest. Enclosures of this type, circular earthen or stone banks enclosing a modest interior, are found widely across Ireland and often predate the medieval period, though without excavation the precise function and date of this one remain unknown.

The site is described as very overgrown, and the marshy ground and steep southern slope would make close inspection awkward. The bank edges are said to be well defined except at that southern drop, so approaching from the north or east would give the clearest sense of the enclosure's form.
