This sub-rectangular earthwork, measuring approximately 31 metres north to south and 29 metres east to west, is defined by a substantial earth and stone bank that reaches up to 6.8 metres in width and stands 1.4 metres high on its exterior face. The bank varies in length around the perimeter; 24 metres on the north side, 33 metres to the east, 29 metres to the south, and 30 metres along the western edge, though midway along the western side it has been reduced to a simple scarp about 4.5 metres wide and a metre high.

The site’s defensive features are particularly well preserved on three sides, with an external fosse, or defensive ditch, running 6 metres wide and nearly half a metre deep along the eastern, southern and western boundaries. To the north, past quarrying activities have partially filled in this feature. A possible entrance, between 2.5 and 3 metres wide, appears to have provided access from the south. Beyond the main fosse, traces of an outer bank survive on the southern and western sides, measuring over 13 metres in width and standing 0.7 metres high on its interior face, though only 0.25 metres on the exterior.

The interior of the enclosure slopes gently downward towards the north, following the natural contours of the landscape. This moated site forms part of a wider medieval landscape in the area, with another enclosure located 590 metres to the east-northeast. Such earthworks were typically constructed between the 13th and 15th centuries, serving as fortified homesteads for Anglo-Norman settlers or prosperous Irish families, combining defensive capabilities with agricultural management of the surrounding lands.
