It measures roughly 38.8 metres north to south and 35.5 metres east to west, and it is defined not by a single boundary but by a layered system: an inner bank, an intervening fosse, and an outer bank beyond that. A fosse, in this context, is simply a ditch, usually dug to complement a raised bank and together forming a defensive or enclosing barrier. The arrangement here suggests something that once meant to keep things in, or out, or both.

The enclosure sits within what was the Rathglass Demesne, the managed lands surrounding a landed estate, though the earthwork itself almost certainly predates any such post-medieval organisation of the landscape. Of the three elements that once defined its perimeter, survival is uneven. The outer bank remains only along the southern side, while the fosse can still be traced on the east, south, and west. The northern side has lost much of its legibility. Inside, in the northern section of the interior, there is a stony depression whose purpose is not recorded. It could be the ghost of a structure, a collapsed feature, or something else entirely. Modern field fencing now follows the east, south, and west sides, and small breaches have been made through the earthwork at various points, the ordinary wear of agricultural use over generations.

The enclosure is in fair condition overall, which in practical terms means enough survives to read the shape and intention of the original, even if the detail has softened. The grassy, level setting within the former demesne lands gives the site an understated quality; there is no dramatic topography to frame it, just the quiet persistence of banks and ditches holding their approximate form in the turf.
