A series of low, grass-covered earthen banks, visible only intermittently across the landscape, marks out what was once a working field system, covering an area roughly 180 metres along a north-east to south-west axis and about 60 metres across. One principal bank runs on a north-west to south-east alignment and can be followed through several fields, with a number of smaller banks branching off it at right angles. Immediately to the north of the castle itself, a separate rectangular enclosure, roughly 40 metres by 15 metres, is defined by its own bank, suggesting a more deliberately bounded space, perhaps for stock or cultivation close to the settlement.

Field systems of this kind are among the least celebrated archaeological features in the Irish countryside, yet they carry considerable information about how land was managed and divided in earlier centuries. The earthen banks, essentially built-up boundaries between cultivated plots or grazing areas, accumulate slowly through use, clearance of stone and soil, and deliberate construction over generations. Their association here with a castle suggests they were part of the same landholding complex, the agricultural infrastructure that supported whoever occupied and controlled the tower. Without further excavation or documentary evidence, it is difficult to assign a precise date, but the spatial relationship between the banks and the castle points to a medieval or early post-medieval origin.
