The result is an unusual truncation that makes the site a small study in colliding timescales, one layer of Irish infrastructure cutting across another that predates it by perhaps a thousand years or more.

The monument sits in level, marshy ground at Aghalacka, a setting that would have suited its original builders well. Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically enclosing a farmstead within a circular earthen bank and ditch. This example, recorded by Denis Power and uploaded to the national record in August 2011, is a reasonably complete specimen despite its condition. The main enclosure is roughly thirty metres in diameter, defined by an earthen bank that rises about three quarters of a metre on the interior side and a more imposing one and a half metres on the exterior. Outside that sits a fosse, the term for a surrounding ditch, some three metres wide and roughly eighty centimetres deep. Beyond the fosse, two further external banks survive in arc-like sections running from west around to the northeast, and from the east-southeast around to the south-southeast. A causeway entrance, nearly three metres wide, is positioned at the northeast, which is a common orientation for ringfort entrances. At the centre of the interior, a shallow and irregular depression may indicate later quarrying activity, suggesting the site has been interfered with at some point after its original use.

Accessing the monument requires care. The surrounding terrain is marshy, and the monument itself is heavily overgrown, particularly across the southern half of the interior where trees and dense scrub have taken hold. Visitors should expect to do more reading of the landscape than viewing of it in any conventional sense; the external banks are easier to trace on the ground than the interior details, and the point where the railway embankment cuts through the northern outer bank is one of the more legible features. The site is best approached in late winter or early spring, before ground vegetation thickens, when the earthworks become easier to distinguish beneath the trees.
