The foundation lines measure roughly five metres along one axis and just under four along the other, with walls about 1.2 metres wide, which is substantial enough to suggest a structure of some permanence, though its age and precise purpose remain unresolved.

The enclosure surrounding it is a rath, the term used for a roughly circular earthen ringfort, typically dating from the early medieval period in Ireland, roughly the fifth to the twelfth centuries. These were the farmsteads and defended homesteads of the period, and finding a structure positioned near the centre of one is not unusual in itself. What is notable here is the shape. The L-plan foundation line does not obviously correspond to the round or sub-rectangular forms most commonly associated with early medieval domestic buildings, which raises the question of whether this structure belongs to the same period as the enclosure at all, or whether it represents something later, built within an already-ancient boundary by people who found it a convenient and ready-made form of shelter or demarcation. The dating remains genuinely open.
