Nobody knows when it was built or who lived there. What survives is a raised earthen platform roughly ten metres by nine, defined by a scarp, a slight stepped edge in the ground surface, and surrounded by a fosse, a shallow defensive or boundary ditch cut into the earth. Around that, remnants of an outer bank, known as a counterscarp, are still faintly legible as low swellings along the northern and eastern sides. Two breaks in the enclosing scarp, one near the north end of the east side and one at the west, may once have served as entrances, though neither can be confirmed with certainty.

What makes this particular earthwork quietly interesting is its position. It lies immediately to the west of a rath, a ringfort of the kind built across Ireland roughly between the early medieval period and the later first millennium, typically as an enclosed farmstead for a family of some local standing. Raths are common in the Irish landscape, but the relationship between this external platform and the rath beside it is less straightforward. A second possible house has been identified within the rath's own interior, which raises the question of whether the two structures were contemporary, sequential, or served quite different purposes within the same small landscape. The platform's interior slopes gently downward to the east, a detail that might reflect drainage concerns, the natural lie of the land, or the slow subsidence of centuries of undisturbed earth.
