This rectangular fortification, measuring approximately 50 metres northeast to southwest and 44 metres northwest to southeast, represents a fascinating example of defensive architecture from Ireland’s medieval period. The site consists of an inner bank constructed from earth and stone, standing about 4.5 metres high on its exterior face, separated from an outer bank by a water-filled ditch or fosse that’s just over 2 metres wide.

The outer defensive bank, built from earth and large limestone boulders, varies between 2 and 4 metres in width and rises to nearly 3 metres in height. Due to the steeply sloping terrain on all sides except the east, considerable slippage has blurred the outer edges of this bank over the centuries. Two causewayed entrances, each about 5 metres wide, pierce the defences at the northeast and southwest corners, with the northeastern entrance curiously divided by a small knoll. Along the eastern section, traces of the original stone facing can still be seen stretching for about 9 metres, whilst a modern field wall now overlies the northeastern portion of the outer bank.

Within the protected interior, a slightly raised rectangular platform measuring roughly 15 by 8.5 metres occupies the centre, its boundaries marked by large boulders and stone construction. The site doesn’t stand alone in the landscape; about 100 metres to the south, two parallel banks with a water-filled ditch between them extend for 20 metres, whilst a pear-shaped raised area lies approximately 120 metres to the southwest. These additional features suggest this was once part of a larger complex, perhaps indicating the location of associated agricultural or defensive structures that supported the main fortification.
