This rectangular enclosure measures approximately 46 metres east to west and 36 metres north to south, with an east-west stream running immediately to its north. The site consists of a grass-covered area surrounded by low earthen banks, each about 8 to 9 metres wide and rising just 0.4 metres high, modest dimensions that belie its historical significance.

The defining feature of this site is its moat system, traces of which remain visible around the perimeter. The southern side preserves the clearest evidence of the outer moat, measuring about 7 metres in width, whilst field banks mark the western and northern boundaries. Modern technology has revealed what ground surveys might miss; aerial imagery from Google Earth clearly shows the cropmark of a moat along the eastern side, a detail first spotted by researcher Simon Dowling in 2018. These cropmarks appear as darker lines in the vegetation, indicating where the deeper, moister soil of the former moat affects plant growth differently from the surrounding area.

Such moated sites were typically constructed between the 13th and 14th centuries, serving as fortified homesteads for Anglo-Norman settlers or prosperous farming families. The rectangular shape and modest size of the Oulartwick Beg example suggests it may have been a manor house platform, where the moat served both defensive and drainage purposes whilst also acting as a status symbol. The site’s location near a stream would have provided a ready water source for filling the moats, an essential consideration in medieval site planning. Today, whilst the earthworks may appear unremarkable to the casual observer, they represent an important piece of Wexford’s medieval landscape, preserving the footprint of a settlement that has endured for over seven centuries.
