This rectangular earthwork, measuring approximately 24.5 metres from northeast to southwest and between 20.5 and 23.5 metres from northwest to southeast, consists of a grass and rush-covered interior space surrounded by substantial earthen banks and defensive ditches.

The site’s defining features include impressive earthen banks on three sides, with the northeastern bank standing particularly tall at 1.45 metres on its exterior face and spanning 5.5 metres in width. The southeastern and northwestern banks, whilst smaller, still form clear boundaries to the enclosed area. Each side originally featured defensive fosses, or ditches, measuring between 3.7 and 5 metres across at the top, though those on the northeastern and southeastern sides have since been modified into drainage channels reaching depths of up to 1.4 metres. An additional outer bank on the southwestern side, rising 1.4 metres high, provides an extra layer of defence to the structure.

This type of moated site typically dates from the Anglo-Norman period and would have served as a fortified homestead for a farming family of some standing in the local community. The presence of another earthwork approximately 180 metres to the southwest suggests this area held strategic or economic importance during the medieval period, perhaps controlling agricultural lands or local trade routes through the Roscommon countryside.
