The earthwork sits about 50 metres from the Owenur River, which flows northeast to southwest through a flat valley roughly 100 metres wide. This location was strategically chosen, as historical records indicate there was once a ford crossing the river at this very spot, making it an important point for controlling local movement and trade.

The site forms an almost perfect square, measuring approximately 29.7 metres north to south and 29.4 metres east to west. What makes this earthwork particularly interesting is its defensive design; the grassy area is enclosed by earthen banks that still stand between 6 and 6.5 metres wide, though time has reduced their height considerably. On the interior, these banks rise only 10 to 20 centimetres, whilst on the exterior they reach 30 to 40 centimetres. Surrounding these banks are the remnants of fosses, or defensive moats, which would have provided an additional layer of protection for whoever occupied this site.

Today, the fosses measure between 4.5 and 6 metres across at their tops, though they’re now only 10 to 30 centimetres deep; centuries of erosion and infilling have taken their toll. The northern fosse has almost completely disappeared, leaving only the faintest trace of what was once part of this site’s defensive perimeter. Despite these changes, the earthwork remains a tangible link to medieval Ireland, when such moated sites served as fortified homesteads for Anglo-Norman settlers or wealthy Gaelic families who adopted this defensive architectural style.
