It measures roughly 42 metres east to west and 28 metres north to south, and what defines it now is less a clear boundary than a much-degraded scarp, still rising between 0.8 and 1.8 metres in places, with fragmentary traces of later drystone walling along its face. The original entrance has been lost entirely, and from the north-east around to the west, the scarp has been modified and folded into an ordinary field boundary, making it easy to mistake the whole thing for a natural rise in the ground.

This is a rath, the commonest type of early medieval enclosure in Ireland, typically consisting of a roughly circular area enclosed by one or more earthen banks and ditches. Raths served as defended farmsteads for the better part of a millennium, from roughly the fifth to the twelfth centuries. What is quietly notable about this particular example is the absence of any fosse, the ditch that would normally accompany the enclosing bank. Whether that ditch was never dug, or simply ploughed and silted into invisibility over the centuries, is not clear. Within the interior, there is a possible house site at the centre, a slight depression or platform that hints at domestic occupation, though the ground here has been grazed and modified enough that the details are difficult to read.
