The earthwork appears on historical Ordnance Survey maps from as early as 1840, where it was depicted as a circular enclosure. By the time the more detailed 1897 map was drawn, surveyors recorded it as an oval-shaped area measuring approximately 16 metres northeast to southwest and 22 metres northwest to southeast.

The monument consists of a raised bank with a wide berm and an external bank that runs from the southeast through west to the northeast. Beyond this point, the earthwork has been reduced to a simple scarp, and along its northeastern to southern section, it now forms part of a field boundary wall. Just 90 metres to the southwest stands a bivallate ringfort, another type of early medieval fortification, suggesting this area held strategic or settlement importance for centuries.

Local historian Barry identified this site in 1981 as a possible moated site, a type of medieval homestead typically dating from the 13th to 14th centuries that consisted of a platform surrounded by a water-filled ditch. Today, the monument remains visible as a shrub-covered outline on aerial photographs, though time and agricultural activity have softened its once-defined edges. Whether it served as a defended farmstead for Anglo-Norman settlers or had an earlier origin remains an intriguing question for archaeologists studying Limerick's medieval landscape.
