Originally just 220 metres away, the shoreline now lies 560 metres to the west following drainage work on the River Inny in the late 1960s. The site occupies poorly drained floodplains, with Farrow Castle visible 400 metres to the northeast, creating a landscape rich in medieval earthworks.

This rectangular raised area, measuring roughly 28 metres northwest to southeast and 35 metres northeast to southwest, represents a classic example of Anglo-Norman defensive architecture. Two earthen banks with an intervening fosse, or defensive ditch, enclose the site. The entrance at the east-northeast features a carefully constructed causeway, six metres wide and half a metre high, crossing the fosse between gaps in both the inner and outer banks. The inner bank reaches its greatest height at the southwest corner and remains best preserved along the northeast side, though disturbance gaps appear at various points. Particularly intriguing is a sub-rectangular mound flanking the entrance, measuring approximately 10.8 by 8.8 metres and rising 1.6 metres high.

The interior slopes gently from northeast to southwest, with a shallow depression running northwest to southeast across the northeast quadrant. A small D-shaped annexe of uncertain date adjoins the northeast side of the monument, whilst a post-1700 drainage ditch runs past the western edge. Despite centuries of weathering and agricultural activity, the earthworks remain clearly defined, offering visitors a tangible connection to Ireland’s medieval past when such moated sites served as fortified homesteads for Anglo-Norman settlers.
