The structure is a ring barrow, a type of prehistoric funerary monument in which a central burial mound is enclosed by a circular ditch, known as a fosse, and an outer earthen bank. The combination of mound, fosse, and bank creates a series of concentric rings when viewed from above, though on the ground the whole thing is subtle enough to be easily overlooked.

Researcher Timoney, writing in 1984, recorded the monument in some detail. The total diameter of the feature runs to around 19 metres. At its centre is a flat-topped mound roughly 10 metres across and no more than 30 centimetres high, enclosed by a U-bottomed fosse some 2.5 metres wide and 40 centimetres deep, with an outer bank 2 metres wide and 35 centimetres high. These are modest dimensions, and the whole structure has grown over with vegetation, which softens its outline further. The site had earlier been catalogued by Göran Burenhult in 1980 under the name Knocknahur North, though that attribution was later corrected to Breeoge. Burenhult's work also included phosphate analysis of the surrounding soil, a technique sometimes used to detect traces of past human activity such as settlement or burial. In this case, the phosphate values showed only very slight increases, offering little in the way of additional evidence about how the site was once used.
