This moated site occupies a prominent ridge that runs northwest to southeast, standing out distinctly from the low-lying, waterlogged pasture that characterises much of the area. The site’s elevated position would have provided both defensive advantages and protection from the boggy conditions that persist in the locality today.

The earthwork’s defensive features remain impressive despite centuries of weathering and neglect. A scarp measuring just over a metre in height marks the inner edge of the fortification, beyond which lies a substantial fosse; a defensive ditch that’s now waterlogged, ranging from 4.8 to 5.9 metres wide and plunging to a depth of 2 metres. Outside this watery barrier, a massive bank constructed from earth and stone rises 2.1 metres high and spans 6.3 metres in width, creating a formidable obstacle for any would-be attackers. These enclosing elements, now overgrown with scrub vegetation, would have formed a sophisticated defensive system typical of medieval Irish fortifications.

While an entrance gap appears on the eastern side, this opening is believed to be a modern alteration rather than part of the original design. Such moated sites were typically constructed during the Anglo-Norman period and later centuries, serving as fortified homesteads for local lords or prosperous farmers. The site at Killyfad and Creeve represents an important piece of Longford’s medieval landscape, its earthen banks and waterlogged ditch preserving the outline of what was once a significant local stronghold.
