The earthwork, positioned 80 metres east of a land drain and 180 metres north of the Ballinlough townland boundary, forms an almost perfect square measuring roughly 16 metres from northeast to southwest and 15 metres from northwest to southeast. What makes this site particularly intriguing is its construction: a raised platform surrounded by the remains of a four-metre-wide bank and an external fosse, or defensive ditch, of similar width. These features are characteristic of medieval moated sites, which were typically built by Anglo-Norman settlers between the 13th and 14th centuries as fortified farmsteads.

The site remained unrecorded on historic Ordnance Survey maps until it was spotted from above during the Bruff aerial photographic survey in 1986. Since then, various aerial images have captured its distinctive rectangular footprint, including orthoimages from the early 2000s through to 2020. The monument’s clarity from the air is remarkable; the earthwork’s outline remains crisp despite centuries of agricultural activity in the surrounding fields.

Situated in a landscape rich with archaeological features, the moated site has some interesting neighbours. Just 140 metres to the north-northeast lies a ring barrow, whilst 180 metres to the south you’ll find St Bridget’s holy well, suggesting this area has been significant to local communities for many centuries. The combination of prehistoric, medieval and religious monuments in such close proximity paints a picture of continuous human activity in this corner of Limerick, where each generation has left its mark on the wet pastures of Kildromin.
