It is modest in scale, roughly eleven metres long and six metres wide, and roughly rectangular in shape, which is itself a little unusual for earthen mounds in Ireland, where circular forms tend to dominate. Its function has never been firmly established.

What little is recorded places it a short distance south of Teampall na Seacht Mac Rí, a church site whose name translates as the Church of the Seven Sons of the King. That dedication alone signals a place with deep roots in early Christian or possibly pre-Christian tradition, and the proximity of the mound to such a site raises questions that the available record does not answer. The mound's dimensions were noted by J. Waddell, and it appears in Tim Robinson's 1980 survey of the area, later finding its way into Paul Gosling's Archaeological Inventory of County Galway, published in 1993. Crucially, the inventory flags that the mound was not visited by its compilers, meaning no ground-level inspection informed the description. Whether it represents a burial feature, a field boundary remnant, or something else entirely remains open.
