It is not dramatic in scale, measuring roughly 13.5 metres north to south, 12 metres east to west, and just under two metres high, but its irregular shape and the limestone slabs that protrude from its base suggest something more deliberate than a field clearance heap. Those slabs may be the surviving traces of a stone revetment, a retaining wall of upright or closely set stones built around the base of a mound to hold its edges in place, a technique associated with prehistoric burial and ritual monuments across Ireland.

What makes the site quietly compelling is that it does not stand alone. A second mound of comparable character lies around 30 metres to the south, in an adjacent field. The pair were noted by Tim Robinson, the cartographer and writer who mapped the Aran Islands in extraordinary detail, with his 1980 survey forming the basis of what is known about the site. Robinson's work on Inis Oírr documented a landscape where prehistoric, early medieval, and later remains are compressed onto a small limestone platform, and these two mounds fit into that layered pattern without yet yielding easy answers about their age or purpose. Whether they are burial mounds, clearance cairns given more formal treatment, or something else entirely remains unresolved.
