They are easy to miss at surface level, their ridges worn down by centuries of weather and land use, but from the air they become legible: a quiet geometry pressed into the landscape, the ghost of an agricultural system that once fed and organised life around a now-ruined castle and church.

The earthworks were captured in oblique aerial photographs taken on 20 July 1968 by the Cambridge University Collection of Aerial Photography, recorded under reference CUCAP AVT004/005. Oblique aerial photography, taken at an angle rather than straight down, is particularly useful for revealing subtle earthworks because low sunlight throws even shallow ridges into shadow, making them readable in ways that ground-level survey often cannot manage. The field system sits to the east of Rockstown Castle, with the castle and its associated church standing to the southwest. The arrangement suggests the fields were laid out in relation to both structures, forming part of the same domestic and agricultural complex. The site is also recorded under monument reference LI023-001, indicating it has been identified, perhaps independently, in a second survey context. The record was compiled by Martin Fitzpatrick and uploaded in July 2020.

The earthworks are not a managed visitor site, and there is no formal access or interpretation on the ground. Rockstown Castle itself, a tower house of the kind built across Munster between the late medieval and early modern periods, provides the most visible point of reference for orienting yourself in the landscape. The field system lies to its east. Google Earth orthoimagery, which offers a straight-down satellite view, can help identify the outlines before a visit, and the original CUCAP photographs remain the clearest visual record of what survives. If you do visit the area, the best conditions for spotting earthworks at ground level are a low winter sun and short grass, when even slight undulations in the soil cast enough shadow to suggest what lies beneath.
