This rectangular enclosure, measuring approximately 51 metres from east to west, consists of two earthen banks with a substantial fosse, or defensive ditch, running between them. The fosse itself spans about 5 metres in width and maintains a depth of roughly 0.7 metres on its exterior side; during site visits, it’s been observed to hold water, suggesting it may have served as a water-filled defensive feature historically. A possible entrance, around 3 metres wide, appears to have been positioned at the northern end of the western side.

The preservation of this site varies considerably around its perimeter. The inner bank, measuring 3 metres wide with an internal height of 0.3 metres and an external height of 1.7 metres, remains the best-preserved element of the fortification. However, time and possibly agricultural activity have taken their toll on other sections; both the fosse and the outer bank, which originally measured 3 metres in width, have been destroyed along a significant arc from the western side, through the northern section, and continuing to the northeastern corner.

This type of moated site typically dates from the Anglo-Norman period in Ireland, roughly from the 13th to 14th centuries, when such fortified farmsteads were constructed to protect agricultural settlements and assert control over newly colonised lands. The information about this particular site comes from the Archaeological Inventory of County Offaly, published by the Stationery Office in Dublin in 1997, though the entry has been revised with more recent research findings as of May 2011.
