It does not announce itself dramatically; what survives is a set of low banks, a ditch, and a question about the engineering choices made by whoever built it. That question is genuinely odd. The inner bank contains large stone slabs set upright along its inner face, but they do not appear to have been a revetment, which is a facing wall used to hold an embankment in place. Instead, they seem to have served as a hidden core, with earth simply heaped over them. It is an unusual construction approach, and one that leaves the slabs functioning more like a buried skeleton than a visible wall.

The site is a rath, the Irish term for a ringfort, a type of enclosed farmstead typically dating from the early medieval period, roughly 500 to 1000 AD, though many continued in use beyond that. Most raths consist of a single bank and ditch, so a double-banked example like this one, with an inner bank, an outer bank, and a fosse (the ditch between them) cutting all the way round, represents a more substantial effort. The overall diameter is 31 metres. The outer bank is only partly intact, surviving from the south-southwest around through the west to the north-northwest, while the fosse remains legible all round. A gap measuring three metres at the eastern side may be the original entrance. The site was noted by Knox in 1918 and examined in more detail by Cody in 1989, both of whom recorded its general form and the peculiarity of its inner construction.
