These modest earthworks, rising only between 0.4 and 0.9 metres in height, outline three contiguous subrectangular plots, each measuring up to around fifty metres across. They sit immediately east of a recorded enclosure, and they predate the larger, more regular fields that now dominate the surrounding landscape. Their very ordinariness is part of what makes them quietly significant: not a monument anyone built to be seen, but a working pattern of land division that has simply, partially, endured.

The banks appear to be remnants of an earlier field system, one that was already laid out before the rectilinear land divisions familiar from post-medieval improvement schemes were imposed across the area. Aerial photographs reveal that the system once extended further to the south and west before land reclamation works removed those portions. What remains is fragmentary, three plots out of what was evidently a more extensive arrangement. Ancient field systems of this kind, boundaries built up gradually from cleared stone and persistent use rather than planned in a single effort, are easily lost to drainage schemes, ploughing, and agricultural improvement. In this case, the gently undulating terrain of the reclaimed pasture at Boleymeelagh has preserved just enough of the original pattern to suggest the larger whole that once existed here.
