Enclosures of this kind are among the most common and most ambiguous features of the Irish archaeological record. The term covers a broad range of structures, from the circular earthen banks of a ringfort, which typically served as a defended farmstead during the early medieval period, to prehistoric ditched enclosures whose purposes remain debated. Without knowing which type this is, the site occupies that quietly frustrating category of places that are known to exist, are considered significant enough to protect, and yet remain largely uncharacterised in any accessible form.

The townland name itself offers a small point of interest. Carrowmoremoy derives from the Irish, likely containing the elements for a large quarter-land division, a naming convention that reflects the old Gaelic system of land measurement still preserved in placenames across Connacht. Mayo as a county is exceptionally rich in earthwork enclosures of all periods, from the megalithic field systems beneath the bog at Céide Fields to the dense scatter of ringforts that dot its interior parishes. Where exactly this particular enclosure fits within that long sequence is, for now, a question the available record cannot answer in any detail.
