Located 255 metres east of the Carrow townland boundary, this rectangular earthwork once formed a substantial defensive structure, measuring approximately 75 by 50 metres. First documented on the 1897 Ordnance Survey Ireland 25-inch map, the site caught the attention of antiquarian Thomas Johnson Westropp, who described it in 1916 as a “straight-sided fort” in what he mistakenly recorded as Bohora.

The monument’s true nature becomes clearer through modern aerial photography, which reveals not just one but two rectangular cropmarks; the main enclosure and a smaller adjoining feature to the south, measuring roughly 60 by 30 metres. These ghostly outlines, visible in orthophotographic surveys taken between 2005 and 2016, represent the remnants of what was likely a fortified homestead dating to the Anglo-Norman period. Such moated sites were typically constructed between the 13th and 14th centuries, serving as defended farmsteads for Anglo-Norman settlers or prosperous Irish families adopting Norman building traditions.

Today, little remains visible at ground level, with the earthworks having been levelled by centuries of agricultural activity. Yet from above, particularly in dry conditions or after light snow, the buried ditches and banks reveal themselves as crop marks, offering a tantalising glimpse of medieval life in rural Limerick. These subtle traces in the landscape serve as reminders that even the most unassuming fields can harbour significant archaeological treasures, waiting to tell their stories through careful observation and documentation.
