Most such earthworks carry the irregular outlines of necessity, shaped by topography, livestock management, or the gradual accretion of field boundaries over generations. This one, roughly tear-shaped and measuring 33 metres north to south and 27 metres east to west, is conspicuously symmetrical, its northern half almost perfectly semicircular. That regularity is unusual enough to prompt questions about what the place actually is.

The enclosure sits within a broader multiperiod field system, meaning the landscape around it accumulated boundaries and divisions across several distinct eras of use and settlement. The 1840 edition of the Ordnance Survey six-inch map records it simply as a small triangular field, which suggests the shape visible today may have been altered or formalised sometime after that survey was made. The northern boundary is defined by a drystone wall, a construction method using unmortared stone, standing 1.4 metres high, with a modern gap opened at the southeast. What makes the symmetry particularly notable is a working theory that it reflects deliberate landscaping rather than agricultural function. The land was once part of an estate, and it is possible the enclosure was shaped, or reshaped, with aesthetic intent, to serve the visual or recreational purposes that often accompanied estate grounds in Ireland during the eighteenth and nineteenth centuries.
