First recorded on the 1907 Ordnance Survey map as a hachured feature, this moated site was documented in detail during the 1940s when it still retained much of its original form. The rectangular enclosure, with its characteristic rounded corners, was bordered by the lake to the north and surrounded on the remaining sides by a substantial fosse or moat that varied in width from about 2 metres on the western side to over 3 metres on the east, with depths reaching up to 1.5 metres in places.

The site featured an internal bank that rose impressively from the moat’s bottom, reaching heights of nearly 2 metres on the eastern and western sides, though its internal elevation was considerably more modest at less than half a metre. This defensive earthwork would have created a formidable barrier in its heyday, particularly given its strategic position near the lakeshore. The proximity to both a church just 50 metres to the west and a crannog approximately 100 metres to the north-northwest suggests this area held considerable importance in medieval times, forming part of a broader complex of ecclesiastical and secular sites along the shores of Lough Melvin.

Today, little remains of this once-substantial monument beyond a slightly raised, grass-covered area measuring roughly 40 metres from northeast to southwest and 30 metres from northwest to southeast. The most tangible surviving feature is a section of earthen bank on the northwestern side, still standing about 75 centimetres high and over 4 metres wide, with faint traces of the external fosse that once defined this intriguing medieval site. Though the monument has largely been erased from the landscape, its recorded dimensions and strategic location offer valuable insights into the defensive structures that once dotted the Irish countryside.
