This rectangular earthwork, measuring approximately 30 metres east to west and 19 metres north to south, consists of a sophisticated triple defence system. An inner bank, roughly 7 metres wide and standing about half a metre high on the inside and nearly a metre on the outside, forms the first line of defence. Between this and an outer bank lies a fosse, or defensive ditch, about 4 metres wide, whilst the outer bank itself spans nearly 5 metres in width.

The western and northern sides of the site show the clearest preservation of these defensive features, with what appears to be an original entrance on the eastern side. Such moated sites were typically constructed during the Anglo-Norman period in Ireland, serving as fortified homesteads for colonists and wealthy landowners. They provided both practical defence and a symbol of status in the medieval landscape, with the water-filled moat serving the dual purpose of protection and potentially as a source of fish.

This particular site forms part of a broader medieval landscape in the area; another square enclosure can be found approximately 680 metres to the southeast. The information about this site comes from the Archaeological Inventory of County Laois, originally compiled in 1995 by P. David Sweetman, Olive Alcock and Bernie Moran, with updates incorporated as recently as April 2019 to reflect ongoing archaeological research in the region.
