It belongs to that category of monument that archaeology acknowledges before it can explain, a feature significant enough to be catalogued but whose character, date, and purpose remain, for now, unelaborated.

Earthworks, as a class, cover a wide range of human-made or human-modified landscape features, from the enclosing banks of a ringfort to the raised profiles of field systems, burial mounds, or the remnants of defended enclosures. Clare has examples of all of these, scattered across its limestone plains and along its drumlin-edged margins. Drumdigus as a place-name has the particular cadence of Irish townland nomenclature, though without further documentation it is difficult to say more about the specific form this earthwork takes or the period from which it dates. It may be prehistoric, early medieval, or something in between. That ambiguity is itself part of what makes it worth noting.
