This rectangular plot of scrub-covered land, measuring 35 metres east to west and 34 metres north to south, represents a medieval defensive structure that would have once served as a fortified homestead or administrative centre.

The site’s defensive features remain clearly visible despite centuries of weathering. Three sides are protected by moats, whilst the western boundary relies on a natural stream about 4 metres wide and 1.5 metres deep. The northern moat retains its flat-bottomed profile, spanning 7.7 metres across at the top and narrowing to 5 metres at the base, with depths ranging from 1.2 metres on the inner side to 1.5 metres externally. An outer bank, still visible along this northern edge, adds an extra layer of defence with its 4-metre base width and half-metre height. The eastern moat has been partially filled in over time but still shows dimensions of 6.2 metres width at the top, whilst the southern moat maintains its round-bottomed shape at 6.5 metres wide with depths reaching 2.2 metres internally.

Archaeological surveys suggest the entire complex, including its outer banks, originally covered an area of approximately 56 metres north to south and 45 metres east to west. These moated sites were typically constructed by Anglo-Norman settlers or wealthy Gaelic families during the 13th and 14th centuries, serving both defensive and status purposes in medieval Irish society. The Ballymichael example, documented in the Archaeological Inventory of County Wexford in 1996 and updated through subsequent research, stands as a well-preserved example of these once-common fortified dwellings that dotted the Irish landscape during the Middle Ages.
