Nearly circular in plan, measuring roughly 11.5 metres north to south and 10.5 metres east to west, it consists of a bank of earth and stone rising about 1.4 metres on the exterior, enclosing a hollow interior. That hollow is the detail that quietly unsettles any confident reading of the site. A ring of raised ground with a depressed centre could point in more than one direction.

The two leading interpretations sit some distance apart in terms of original function. The structure may once have been a house, perhaps a small circular dwelling of the kind common in early medieval Ireland, where low earthen and stone banks formed the foundations or enclosing walls of a domestic space. Alternatively, it could be a barrow, a burial mound, in which case the hollow centre might indicate robbing or collapse over centuries rather than original design. A quantity of stone concentrated in the western half of the interior adds a further layer of ambiguity; it could represent the remains of internal revetment, a lining of stones used to stabilise the inner face of the bank, or it could be the result of later disturbance. A later field wall has been built directly over part of the bank, running from the north-north-east to the south-east, and a gap on the south-east side may be a relatively modern opening rather than an original entrance. The landscape around it has been put to agricultural use for long enough that distinguishing ancient deliberate stone from accumulated field clearance is not straightforward.
