A rath, or earthen ringfort, sits on the northern edge of an east-west ridge in Donaghintraine, and part of its enclosing bank has been absorbed into the field boundary that marks the border with the neighbouring townland of Carrowcor. The earthwork has not been cleared away or ploughed under; it has simply been put to work, its ancient form quietly pressed into service as a modern boundary.

Ringforts were the dominant form of rural settlement in early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. They were enclosed farmsteads, the bank and fosse (a surrounding ditch) providing both a degree of security and a clear demarcation of domestic space. This example is a modest but well-preserved specimen: a raised circular platform just under twenty-one metres in diameter, ringed by an earthen bank roughly four metres wide, with an internal height of about a metre and an external height of around one and a half metres. Along the south-eastern to south-south-western arc, that bank has been modified and folded into the townland boundary. The northern side tells a slightly different story: a narrow, shallow fosse only about thirty centimetres deep, accompanied by a low counterscarp bank on its outer edge, both of which appear to be relatively recent additions rather than original features. The original entrance into the enclosure has not survived in any recognisable form.
