Located roughly 200 metres from the lake’s edge, this impressive earthwork commands sweeping views across the surrounding countryside. The monument consists of a large trapezoidal enclosure measuring 72 metres north to south and 58 metres east to west, defined by a series of defensive banks and ditches that have weathered centuries of Irish seasons.

The site’s construction follows the classic medieval pattern of concentric defences; an inner bank built from earth and stone, a fosse (defensive ditch) running around the perimeter, and traces of what was once an outer bank. Time has taken its toll on these features, with the inner bank now appearing wide and low, breached in several places where livestock or later human activity has broken through. The northwest corner retains a slight elevation, whilst the southeast and southwest corners have been worn down and flattened over the years. The fosse that once provided formidable protection is now almost completely filled in, visible only as a subtle depression in the landscape.

Within the enclosure, the ground rises gently towards the centre, though any structures that once stood here have long since vanished. A curious curved bank cuts across the northeast corner of the interior; its purpose remains unclear and may represent a later addition to the site rather than part of the original medieval design. No clear entrance survives, leaving visitors to wonder where the original inhabitants would have crossed these defences to reach their fortified home. Despite its worn appearance, the monument still impresses with its scale and the engineering effort it represents, a substantial medieval earthwork that has endured for perhaps 800 years on this Westmeath hillside.
