When surveyed in 1975, this rectangular earthwork measured approximately 74 metres northeast to southwest and 46 metres northwest to southeast, enclosed by a low bank constructed from earth and stone. The site featured a wide, shallow fosse, essentially a water-filled ditch, along its southeastern and southwestern sides, whilst modern drainage had been installed along the remaining two sides. Though the original entrance could no longer be identified even then, the monument clearly represented a significant medieval settlement.

These moated sites, dating primarily from the 13th and 14th centuries, were typically constructed by Anglo-Norman settlers as fortified farmsteads. The surrounding water-filled ditch served both defensive and drainage purposes, whilst the raised platform within would have supported timber buildings, perhaps a hall house and associated structures. Such sites are particularly common in the Irish midlands, where the relatively flat terrain and clay soils made their construction practical.

Unfortunately, agricultural activity has since levelled the monument, leaving only the faintest traces visible in the pasture today. Despite its deteriorated state, the site holds sufficient historical importance to warrant protection under a preservation order issued in 1972. This legal protection, made under the National Monuments Acts, ensures that any remaining archaeological features beneath the surface are safeguarded for future study, even if little remains visible to the casual observer walking through these quiet Longford fields.
